19-3 Trouble shooting - Take note of the following

Select scan cannot operate in conjunction with mode scan. Select scan is disabled when priority is
engaged.
Priority is disabled when the band scope is in operation. If a long DELAY time is set, priority 'eats'
away at delay time causing it to shorten. If the optional CT8200 slot card is in use, CTCSS SEARCH
cannot operate with priority engaged due to the required CTCSS search time being quite long.
When POWER SAVE is on, response from the AR8200 may be sluggish and there will be periods of no
receive.
If the key is being used to display a frequency with FREQUENCY OFFSET in use, this offset
frequency cannot be stored into memory.
The squelch may not operate promptly (as you may expect) when monitoring in USB, LSB, CW and
NAM modes due the narrow bandwidths employed. This is a fundamental characteristic of the squelch
circuit. Audio may remain even though the "S" squelch legend may have disappeared for a couple of
seconds. It is suggested that LEVEL squelch be used as an alternative in this situation.
There are no internal operator adjustments. In the unlikely event of servicing being required,
please contact your dealer for technical assistance.
