GP140 USER GUIDE
Power Level
You can transmit your calls at different transmit 
power levels. A higher level means you can reach a 
radio that is farther away. Lower power level 
conserves battery power. You are advised to 
transmit as frequently as possible on low power, and 
use high power only when needed.
Press the programmed 
Tx Power
 button to toggle 
between the options for High or Low power transmit 
level. A positive indicator tone indicates that the 
radio is operating in low power mode, while a 
negative indicator tone indicates that the radio is 
operating in high power mode.
SCAN
You can monitor several channels in order to receive 
any call that is transmitted on any of these channels. 
Sixteen different channels can be programmed into 
a scan list. Each channel can share the same scan 
list or have different scan lists assigned to them.
Once the radio’s scan operation is activated and the 
radio detects a call coming through a channel in its 
scan list, it switches to that channel for you to 
receive the call.
Starting or Stopping a Scan Operation
The LED Indicator will blink (green) during a scan 
operation. It will stop blinking when the radio 
switches to a channel.
Talkback
If the programmable Talkback option is set, you can 
respond to any calls received during the scan 
operation by pressing the PTT before the 
programmed hang-time ends. Check with your 
dealer for details.
