SYMPTOM  POSSIBLE PROBLEMS  SOLUTIONS 
On an analog 
channel, irrelevant 
communications 
and/or noises are 
heard. 
Other radios may be using the same 
radio frequency. 
Adjust the squelch and/or consult with your 
radio dealer as necessary. 
The radio may be programmed without 
signaling, but signaling is needed. 
Consult with your radio dealer as necessary. 
On a digital channel, 
you cannot 
communicate with 
others but there is a 
receive indication. 
The ID may be inconsistent with other 
members. (The digital signal is being 
received but not fully demodulated.) 
Set the ID to the same as the other member’s 
radios. Consult with your radio dealer as 
necessary. 
Noisy 
communications. 
Out-of-
range (too far away from) of 
others, or from the channel’s repeater/-
base station. 
Change your location. Moving a few 
yards/meters in one direction 
or moving to a 
higher elevation 
can sometimes greatly 
improve communications range. 
A nearby device, such as an electric 
motor or light bulb, is causing interfe-
rence on the radio frequency/channel. 
Change your location. Moving a few 
yards/meters in one direction can sometimes
greatly improve communications. 
Keypad does not 
operate. 
The keypad has temporarily failed. 
Restart the radio by turning it off and back 
on. 
Display does not 
operate. 
The display has temporarily failed. 
Restart the radio by turning it off and back 
on. 
GPS cannot 
determine 
location/position 
The GPS antenna is improperly con-
nected to the radio, or the antenna is 
damaged/missing. 
Connect the antenna and/or consult with your 
radio dealer as necessary. 
No GPS signal is being received. 
Change your location  and  re-
check for a 
signal.
