Always adjust the volume to the lowest level be- fore listening to unknown transmissions. 2. Use the lowest reasonable level consistent with hearing safety. 3. Don’t use high sound levels in the earphone to overcome high ambient sound levels. That is ab- solutely foolish! Demand and use high isolation earphones. 4. Don’t expose your ears to sound levels that cause them to ring. If your ears do ring after exposure, think of it as a warning bell telling you not to do that again. OSHA (Occupational Safety Health Administration) guidelines on the maximum allowable time exposure to sound pressure levels that will cause hearing dam- age are as follows: 8 hours at 90 dB SPL 4 hours at 95 dB SPL 2 hours at 100 db SPL 1 hour at 105 dB SPL 30 mins at 110 dB SPL 15 mins at 115 dB SPL NEVER expose your ears to 120 dB SPL or higher! Damage will occur. Safety Notes FCC Notice NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pur- suant to Part 15 of the FCC Rules. These limits are de- signed to provide reasonable protection against harmful interference in a residential installation. The equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encour- aged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna • Increase the separation between the equipment and receiver • Connect the equipment into an outlet on a circuit different from that which the receiver is connected • Consult the dealer or an experienced radio/TV tech- nician for help Changes or modifications to this equipment not ex- pressly approved by Lectrosonics, Inc. could void the user’s authority to operate it. Industry Canada Notices Operation of this device is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept interference, including interference that may cause undesired operation of the device. This device has been designed to operate with the antenna listed below, and having a maximum gain of 6 dB. Antennas not included in this list or having a gain greater than 6 dB are strictly prohibited for use with this device. The required antenna impedance is 50 ohms. • Lectrosonics M4T Antenna; P/N 21422 • Linx Technologies model ANT-916-CW-HWR-RPS To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communica- tion. QUADRA LECTROSONICS, INC. 4 System Overview The Quadra system provides an entirely new level of audio and RF performance in a wireless monitor system.

All voltage measurements referenced to circuit common All DUT (transmitter) audio signal inputs and test receiver audio signal outputs are differential Logic Probe equipped with Pulse Memory (Meterman LP25A or equivalent) used in Bit error test All Reciever audio signal measurements taken with 300Ω load resistors from XLR pin 2 to XLR pin 1 and from XLR pin 3 to XLR pin 1. "Factory" mode contains an expanded menu for product testing. To enter factory mode, push and hold front panel MENU/SEL button while powering up DUT This test requires a test receiver wired for access to the bit error signal (baseband board TP24) It is noteworthy that the USB port is useful only for upgrading firmware.
