Call Button • To alert another person that you are calling: 1. Press and release the Callbutton. The other person will hear a two second call tone. You cannot send or receive transmissions during the two second call tone. See page 22 on how to select from 10 available call tone settings. Selectable High•Low Power Output • When in close proximity to another party or during favorable conditions, you can switch from Highto Low Powerto extend battery life. This feature applies to GMRS Channels 1 through 7 and 15 through 22 only. Channels 8 through 14 operate exclusively on low power. To toggle between high and low power: 1. Press and hold the Hi•Low/Enterbutton for two seconds. When using Channels 1 through 7 and 15 through 22 on high power, the Hiicon will be visible on the display. When using those channels on low power and on Channels 8 through 14, the Lowicon will be visible on the display. Display Illumination • To illuminate your display: 1. Press and release the Light/Max Range button to illuminate the display for 10 seconds. Low Power Icon Hi Power Icon Operation Hi•Low/Enter Button Auto Squelch/Maximum Range • Your microTALK ® radio is equipped with Auto Squelch, which automatically shuts offweak transmissions and unwanted noise due to terrain and conditions. This slightly reduces the Maximum Range at which signals can be heard. You can turn off auto squelch to allow all signals to be received and extend the maximum range of your radio. To briefly turn off auto squelch: 1. Press the Light/Max Rangebutton for less than five seconds. If you hear two beeps, you have turned the maximum range extender on(see below). To turn maximum range extender on: 1. Press and hold the Light/Max Rangebutton for at least five seconds until you hear two beeps which indicates the maximum range extender is on. To turn maximum range extender off: 1. Press and release the Light/Max Range button or change channels. Lock Feature • The Lockfeature locks the Channel, Lock/Modeand Hi•Low Power/Enter buttons to prevent accidental operation. To turn the lock feature on or off: 1. Press and hold the Lock/Modebutton for two seconds. A double beep sound is used to confirm your lock onor offrequest. When in Lock mode, the Lockicon will be displayed.

Your range will vary depending on terrain and conditions. In flat, open country your radio will operate at maximum range. Buildings and foliage in the path of the signal can reduce the range of the radio. Dense foliage and hilly terrain will further reduce the range of the radio. On FRS channels 8 through 14, your radio automatically switches to low power, which will limit the range the radio can communicate. Remember, you can achieve maximum range by using maximum range extender. See page 5 for details. Scrolling through Mode Functions • By scrolling through the Mode Functions, you will be able to select or turn on/offpreferred features of your microTALK ® radio. When scrolling through the Mode Functions, your radio features will be displayed in the following order: Set CTCSS Privacy Codes Set DCS Privacy Codes Set NOAA All Hazards Radio Channel Set VOX On/Off Set VOX Sensitivity Level Set Memory Locations Set Channel Scan Set Privacy Code Scan Set Memory Location Scan Set VibrAlert ® and/or Call Alert Set Call Tones Set Roger Beep On/Off Set Keystroke Tones On/Off Scroll through the mode functions using the Lock/Modebutton.
