MANUALLY TUNING THE ANTENNA
38 ENVOY™ TRANSCEIVER REFERENCE MANUAL
Manually tuning the antenna
WARNING: Before using the antenna system see the safety information provided.
NOTE: If the transceiver is connected to an automatic tuning antenna, it tunes
the antenna automatically when required.
You may need to manually tune the antenna if you are receiving on a new channel, or
if you want to check the SWR value for the antenna.
To manually tune the antenna:
1 Press TUNE.
The SWR, battery voltage, and type of antenna tuner are shown on the screen.
1 Hold down PTT to start the tuning process.
The transceiver makes a series of short beeps.
An SWR of less than 2:1 is acceptable.
NOTE: If PTT is held for more than 2 minutes, tuning is automatically
aborted. The transceiver displays a message to inform you of
this, makes an error beep, and returns you to the screen from
which you began.
1 Release PTT to stop tuning.
The beeps cease and you are returned to the screen from which you began.
