record the control settings thus facilitating rapid re-adjustment when changing
channels.
The tuner is physically small and the appearance and finish matches CODAN
transceivers.

2m (approx. 6 ft.) of co-axial cable is provided for connection to the
transceiver.

OPERATING INSTRUCTIONS
1. Connect
the 7208 tuner to the transceiver, earth and antenna as detailed in the
transceiver installation instructions.
2. Select
the desired channel, select AM or TUNE and switch transceiver ON Set LOAD to 6
and ANTENNA to B.
Transmit and slowly rotate the TUNE control
locking for a
peak in the meter reading.
If a peak cannot
be found repeat using different ANTENNA positions.
When the peak is found rotate LOAD to find the position giving the highest meter
reading retrimming TUNE if necessary.
Note the LOAD, TUNE and ANTENNA positions on the scale provided on the front of
the tuner.
Each time the channel is re-selected LOAD and
ANTENNA may be set from the logging scale.
TUNE must be adjusted for peak meter reading using the
..
incomplete.
