This will ensure optimum performance for the GMRS1100-2CH. Battery charging time is typically 10-12 hours. Use of the Audiovox charger with other brands of batteries is not recommended as battery charging times will vary. Refer to the manufacturer’s instructions for charging other brands of batteries. Batteries There are three methods of powering the GMRS1100-2CH: 1. Alkaline Batteries. WARNING: Do not attempt to recharge Alkaline batteries. 2. Audiovox Rechargeable Ni-MH Batteries - (Rechargeable Ni-MH batteries, Wall Adapter and Charging Stand included). 128-6297 6 of 24 6 2.

Once the applicant received his file copy of the report, he questioned us on the output power. They then advised us of a switch that we should have used to change the device to HIGH output power. We rechecked their high output power and found that it is .8 Watts instead of the reported .23 Watts reported. I’ve uploaded a modified test report reflecting the correct output power of .8 Watts and this letter will serve as a request to correct the 731 form. No modifications were made to the device; the output power measurement was taken on the original sample sent to us for testing purposes. Should you have any questions with regards to this, please advise. Regards, Sharon A. Hoffman

Page 2 of the tuning procedure has been revised and uploaded to the file. 2. The transceiver has a power setting potentiometer (RV301) for setting the FRS output power levels on the FRS channels. The microprocessor activates a transistor that limits the output power on FRS channels. The LCD display of the transceiver displays a G or F on the appropriate channel to let the customer know that they are on an FRS or GMRS channel. 3. The output power reported is radiated using the substitution method. The test report has been modified to show this and has been uploaded to the file. 4. The device was tuned up to the proper values in the tuning procedure when the device was tested. 5. The user’s manual has been modified to show that a license is required for the GMRS channels. A notice will also be placed inside the box. I’ve uploaded the revised user’s manual for your reference. Should you have any questions or require any further information, please advise.

I’ve uploaded the contents of the informational insert that the applicant will include inside the box. 2. The manufacturer has questioned the request for a SAR report since the highest output power measured was 0.8 Watts. We thought that PTT radios with an output power of 1.5 Watts and above were required to be tested for SAR. They have modified their tuning procedure to match the measured output power. Should you have any questions or require any further information with regards to this, please advise. Regards, Sharon A. Hoffman

Timco Engineering Inc. 849 NW State Road 45 Newberry FL 32669 Page 1 of 2 From: Mario de Aranzeta [email protected] To: Joe Dichoso [email protected] FCC Application Processing Branch Re: FCC ID OTVGMRS1100 Applicant: SB Telecom Co. Ltd. Correspondence Reference Number: 22708, 22710 731 Confirmation Number: EA479274 1) The previous tune up procedure indicated 2W conducted for GMRS frequencies and 0.5 W for FRS frequencies. This produced an ERP of .8 W for GMRS and .23 W for FRS. The last tune up procedure now indicates only .78 W conducted for GMRS and NO procedure for the FRS. Please submit a corrected tune up procedure for both GMRS and FRS. 2) Since you lowered the tune up procedure from 2 W to .78 W on the GMRS channel, new radiated and ERP measurements are required. Based on radiated ERP measurement of .8 W when the device was tuned at 2 W conducted output, the ERP for the GMRS should be about .312 W. Please confirm with measurements after the device output on the GMRS frequency is tuned to the .78 W. Joe, I’ve talked to the customer and after a lot of interpreting have come to the understanding from them that they misunderstood the previo us email questio ns. I’ve taken o n the respo nsibility of answering the questions o n the tune up procedure here. On 3/28/02 in correspondence 22462. 1) The tune up procedure indicates only 2 W conducted output power. The circuit description indicates 2 Watts conducted output power for GMRS and .5W FRS. How is the output power properly tuned (or fixed) on the FRS channels? (The output power in the FRS channels must not be tuned to GMRS output power levels). Yes the tune up procedure and user’s manual did indicate that a conducted power of 2 Watts may be possible on a GMRS channel. The tune up procedure enclosed as page 2 now includes a procedure for both GMRS and FRS channels. In this procedure, we have limited the output po wer to 1.9 Watts conducted. This sho uld not change the radiated as reported in the test report by any significant amo unt. We are also uploading a revised user’s manual that co ntains the correct o utput power information. Based on these measurements, this indicates that the gain of the antenna is negative which is supported by the ERP power of 0.78 Watts for the GMRS and 0.23 Watts for the FRS.
