Both are general purpose locators used to detect buried pipe and cable services in a variety of situations. The operations of the two systems are very similar. The main difference is in the operational frequencies: • VM-550 Frequencies: 50 or 60Hz, 8 kHz, 83 kHz • VM-560 Frequencies: 50 or 60Hz, 8 kHz, 480 kHz The VM-550/VM-560 is supplied with 1 watt transmitter with both direct connection and induction capabilities. An inductive clamp and LPC live separation filter are also available as optional accessories. To make a direct connection to a pipe or a de-energized cable conductor or cable sheath. To make a ground connection to complete a direct connection circuit. To make an inductive coupling connection to a live cable or pipe.

NOTE The battery condition as indicated on battery icon. Replace batteries if necessary. See Changing Batteries Section. Changing the Locate Frequency Press and hold the depth measurement/frequency selection pushbutton until the frequency menu is entered. The display will show the present frequency selected in large numeric’s in the centre of the screen. Use the “+” or “–” pushbuttons to select the desired frequency. Press the depth measurement/frequency selection pushbutton to re-enter the locate screen. Locating a Cable in the Power (50/60Hz) Mode 1. Hold the locator vertically in the area that is required to be searched. Press the “+” or “-” pushbuttons to set the gain so that the bar graph reads approximately 50%. 2. Hold the locator in front of you in the orientation shown below. 3. Sweep the locator left to right along the suspected route of the cable. As the locator approaches the cable the meter reading will increase. Pinpoint the position by detecting the largest signal. Adjust the sensitivity of the locator by pressing the “+” or “-” pushbuttons to keep the signal on scale. 4. To confirm the direction of the cable, rotate the locator until the largest signal is detected. The direction of the cable is then directly ahead. 5. Continue to locate the cable along the route. 6. Depth measurements are not possible in the power (50/60Hz) mode, if pressed by accident it will show N/A. WARNING The power mode is used to detect signals radiating from cables or services that are carrying a 50 or 60Hz load. It is possible for a cable to be live but not carry a load. In this case there may not be a signal to be detected. Similarly, if a cable is exactly balanced the resulting signal radiating from the cable may be zero and therefore not detectable. Do NOT use the VM-550/VM-560 to identify if cables are live. Always dig with caution. Active Cable and Pipe Locating Detecting a cable or pipe can be achieved by applying a locate tone to a cable or pipe from a transmitter. This is called active locating. The locate tone can be applied by either. • Direct Connection • Induction Mode • Signal Clamp Mode Direct Connection Mode This method involves making a direct connection to the Cable or Pipe. WARNING DO NOT attempt to make a connection to a live conductor. Only make a connection to de-energized or dead cables. It is possible to connect to the sheath of active cables but this should only be attempted by qualified and authorized personnel. Method: Plug the direct connection leads to the transmitter. Connect the red lead to the cable or pipe and the black one to a suitable ground. Ideally this should be a ground stake placed at right angles to the probable route of the target line. If it is not possible to use a ground stake, connect the black lead to a grounded structure such as the rim of a manhole cover or other buried metallic structure. Try to avoid fencing as this will create interference from the return signal travelling along the fence. If necessary clean the connection point with a wire brush to ensure a good electrical connection. Select the desired frequency by pressing the “f” pushbutton. As a general rule the higher frequency will have a cleaner more stable reading and will jump insulation joints on pipes but has the disadvantage that it is more likely to jump to other utility nearby. The lower frequency is better for tracing a particular utility as it is more likely to keep to the utility line the transmitter is attached to. If in doubt, start with the lower frequency and switch to the higher one if it is not possible to detect a stable reading. The same applies to setting the signal level.

Declaration about FCC approval American Certification Body, Inc. 6731 Whittier Avenue Suite C110 McLean, VA 22101 To Whom It May Concern: We, ______Vivax-Metrotech (Shanghai) Ltd._____ are aware of the fact the device under 15.213 shall be verified pursuant to the procedures in Subpart J of part 2. Nevertheless, certification is chosen as the approval method of this product. Thank you, Print name: Snow yang On behalf of Vivax-Metrotech (Shanghai) Ltd. July 30, 2012

022311 – 6 Request for Confidentiality Date: ____ 2012-06-18_____ Subject: Confidentiality Request for: ______FCC ID:N6N2012061803HE_____ Pursuant to FCC 47 CRF 0.457(d) and 0.459 and IC RSP-100, Section 10, the applicant requests that a part of the subject FCC application be held confidential. Type of Confidentiality Requested Exhibit Short Term PermanentBlock Diagrams Short Term External Photos Short Term Permanent* 2 Internal Photos Short Term Permanent Operation Description/Theory of Operation Short Term Permanent Parts List & Placement/BOM Short Term Permanent Tune-Up Procedure Short Term Permanent Schematics Short Term Test Setup Photos Short Term Permanent* User’s Manual *Note: ______(Insert Explanation as Necessary)______ _____Vivax-Metrotech (Shanghai) Ltd.____ has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Permanent Confidentiality: The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Short-Term Confidentiality: The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of ___160 3 ___ days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify ACB in the event information regarding the product or the product is made available to the public. ACB will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04-1705. NOTE for Industry Canada Applications: The applicant understands that until such time that IC distinguishes between Short Term and Permanent Confidentiality, either type of marked exhibit above will simply be marked Confidential when submitted to IC. Sincerely, By: _____ ________ __________ Snow yang_________ (Signature/Title 4 ) (Print name) 2 - The asterisked items (*) require further justification before permanent confidentiality will be allowed. These also currently require review by the FCC under their Permit-But-Ask policy before the grant is issued and can delay completion of an application. Further justification should be added to the note above. One such example for a potted device would be: “The EUT is FULLY potted using a non-removable epoxy based material. Removal of potting material causes irreparable damage to internal circuitry. See photographs exhibits that outline the device before and after potting.” 3 - Please refer to http://acbcert.com/documents/misc-docs/Memo-Short-Term-Vs-Standard-Confidentiality.pdf for complete details. 4 - Must be signed by applicant contact given for applicant on the FCC site, or by the authorized agent if an appropriate authorized agent letter has been provided.

From the rules, it seems verification only for a 15.213 device. However the manufacturer wants to use more stringent route ?certification? for a cable locating equipment. Now we are seeking FCC if you can permit the certification for this 15.213 device? Thank you very much! Ivan Wen/ACB Response: You can apply for certification for this device under the condition that you file an attestation statement that clearly states that this device only requires verification and by electing certification Page from 2007 TCB worshop 2 Do not reply to this message.
