1. Insert the fuses into the power leads.

2. TM8255 radios only.

Switch on the radio to confirm that it is operational (see 
“Turning the radio on and off” on page 19).

Important: Do not transmit yet.

3. Connect an in-line power meter between the radio and 

the antenna and measure the forward and reflected 
power levels.
Less than 4% of the forward power should be reflected. If 
this is not achieved, check the installation, including the 
antenna length.

4. TM8255 radios only.

Once the reflected power levels are within tolerance, 
make a call to another party on the radio (see “Selecting 
a channel or group” and “Making a call”, on page 20).

Contact your radio provider for further information.
