RADIO PICTURE HERE GMRS520 – User Instruction Guide – Content Draft TriSquare Communications Version 0 (11/9/01) Page 2 INSTALL THE BATTERIES Your GMRS520 radio uses 3 AAA Alkaline batteries. To install Alkaline batteries: 1) Make sure your radio is OFF. 2) Remove the battery compartment door by pressing the top and sliding it down allowing the door to be removed. 3) Install 3 AAA Alkaline batteries (not included) into the battery compartment. Be certain to follow the + and – symbols in the compartment. Installing the batteries incorrectly will prevent the unit from operating. 4) Replace the battery compartment door. USING THE RADIO In order to get the most out of your new radio, read this reference guide completely before attempting to operate the unit. Turning the Radio On and Adjusting Volume 1) Press and hold the on/off/mode key for 2 seconds to turn the unit ON. 2) Press and hold the on/off/mode for 2 seconds to turn the unit OFF. Adjusting the Sound (Key Beeps) Your radio emits a beep each time one of the buttons is pressed or a Call tone is generated. To turn the sound OFF, press the Call button while turning on the radio. Repeat this step to turn the sound ON. Choosing a Channel Your radio has 22 channels you can use to talk to others. In order to speak to someone, each of you must be set to the same channel. To choose a channel: Press and release the on/off/mode key to change the mode from volume control to channel control. Press the Up or Down button to increment or decrement the channel number displayed. GMRS520 – User Instruction Guide – Content Draft TriSquare Communications Version 0 (11/9/01) Page 3 Talking on Your Radio To talk to others using the radio PTT button: 1) Press and hold the PTT button and speak in a clear, normal voice about 2-3 inches away from the microphone. While you are transmitting, the transmit icon will be shown on the display. To avoid cutting off the first part of your transmission, pause slightly after pressing the PTT button before you start talking. 2) When you are finished speaking, release the PTT button. You can now receive incoming calls. While receiving, the receive icon will be shown on the display. Transmitting a Call Alert Tone: Your GMRS520 radio is equipped with a call tone that will be transmitted when the Call button is pressed. To transmit the call alert tone, press the Call button. The tone will automatically be transmitted for a fixed length of time. Channel Scan Feature Your GMRS520 radio has a channel scan feature that allows you to easily scan all 22 channels. When an active channel is detected, the unit will pause on that channel until the channel is clear. Then after a 4 second delay, the unit will continue scanning. Pressing PTT while the scan is paused on a channel will allow you to transmit on that channel. To turn on channel scanning: Press and hold either the Up or Down button until the radio has moved through 14 channels. The channel number on the display will be rapidly cycling through the channels. To turn off channel scanning: Press and release either the Up or Down button. GMRS520 – User Instruction Guide – Content Draft TriSquare Communications Version 0 (11/9/01) Page 4 Auto Squelch Feature The radio is equipped with an automatic squelch system, which shuts off weak transmissions and unwanted noise due to terrain conditions or if you have reached your range limit. Automatic Power Save Feature Your radio has a unique circuit designed to dramatically extend the life of the batteries. If there is no transmission within 5 seconds, your radio switches to the Power Save mode. The radio is still able to receive transmissions in this mode.

Operational Description The GMRS520 radio is a self-contained transceiver unit intended for use as a general communication tool. Per the FCC definition: GMRS is a land mobile radio service available to persons for short distance two-way communications to facilitate the activities of licensees and their immediate family members. The GMRS520 model has 22 channels of which channels 1-7 share the FRS channels 1-7. Other features include a CTCSS system with 38 pre-defined, user selectable sub-audible tones for channel quieting. The useable range, while dependent upon terrain and other radio propagation principles, is typically two miles based on the transmit power specified at 0.5 watts ERP. Product features are as follows:

A. INTRODUCTION The following certification data are submitted in connection with this request for type certification of the GMRS 520 transceiver in accordance with Section 2, of FCC Rules. The GMRS 520 is a hand-held, battery operated, UHF, frequency modulated, transceiver intended for voice communications applications under Part 95 GMRS (channels 1-7 or 15-22)* or Part 95 FRS (channels 8-14)*. *See Appendix A for frequency assignment. 1. The unit’s antenna meets 95.647, (i.e. is integral to the transmitter). 2. Except for power, the technical parameters for operating on all the channels (both FRS and GMRS) are the same as those for FRS, (i.e. 12.5 kHz bandwidth, 2.5 ppm frequency tolerance, maximum 2.5 kHz deviation, etc). 3. A notice is included in the user instructions that clearly informs the consumer (buyer/owner) when the radio is transmitting on GMRS frequencies, that operation on GMRS frequencies requires an FCC license and such operation is subject to additional rules specified in 47 CFR Part 95. B. GENERAL INFORMATION REQUIRED FOR TYPE CERTIFICATION (Section 2.1033 of the Rules) 1. Name of applicant: Trisquare Communications Inc. 2. Identification of equipment: FCC ID: O9GGMRS520 a.

Data for 2.1046 through 2.1057 follow this section. C. RF POWER OUTPUT (Section 2.1046 of the Rules) ERP(d) by substitution: FRS 0.48 W GMRS 0.49 W D. MODULATION CHARACTERISTICS (Section 2.1047) 1. A curve showing frequency response of the transmitter is shown in Figure 1. Reference level was audio signal output from a Boonton 8220 modulation meter with one kHz deviation. Audio output was measured with an Audio Precision System One TRMS voltmeter and tracking generator. 2. Modulation limiting curves are shown in Figure 2, using a Boonton 8220 modulation meter. Signal level was established with an Audio Precision System One. The curves show compliance with Section 2.1047 and 95.633(b). 2 D. MODULATION CHARACTERISTICS (Cont.) 3. Figure 3 is a graph of the post-limiter low pass filter which meets the requirements of paragraph 95.633(b) in providing a roll-off of 60Logf/3 dB where f is audio frequency in kHz. Measurements were made following EIA RS-152B with an Audio Precision System One on the Boonton 8220 modulation meter audio output. 4. Occupied_Bandwidth (Section 2.1047 and 95.629(a) of the Rules) Figure 4a is a plot of the sideband envelope of the transmitter output taken with a Tektronix 494P spectrum analyzer on GMRS Channel 1. Modulation corresponded to conditions of 2.1049(c)(1) and consisted of a 2500 Hz tone at an input level 16 dB greater than that necessary to produce 50% modulation at 1998 Hz, the frequency of maximum response. Figure 4b is a plot under the same conditions for FRS Channel 8. The plots are within the limits imposed by Section 2.1049 and 95.635(b)(1)(3)(7)for frequency modulation. The horizontal scale (frequency) is 10 kHz per division and the vertical scale (amplitude) is a logarithmic presentation equal to 10 dB per division. 5.
