Setting sleep timer
The sleep timer turns the transceiver power OFF au-
tomatically after passing the set period. The timer can
be set to 5–120 minutes in 5 minute steps.
The sleep timer function counts the ‘minute’ units,
and does not count the ‘second’ units. For example,
when the sleep timer is started at 12:00 59, first one
minute past for just 1 second. The maximum error is
therefore 59 seconds. This is normal, not a malfunc-
tion.
