Operation Time
Using alkaline cells, typical operation time is from about 12
to 24 hours depending on sound volume and how often the
backlight is on. Other factors that affect the operation time
will include chemistry of the battery (many of the new high
performance batteries, such as the "Duracell® ULTRA" last
10%-20% longer than conventional alkaline cells under high
demand applications). Operation at lower temperatures will
also reduce battery life.
To preserve battery life, the SR-20 will automatically shut
down after 1 hour of no key presses. Simply power the unit
on to resume use.
Low Battery Warning
When the battery gets low, a battery icon
appear in the map area on the screen.
Figure 8: Low-Battery Warning
Just before complete shut down there will be a
non-interruptible power down sequence. An extended buzz
will sound when the SR-20 is about to go into shutdown
sequence.
NOTE: Voltage on rechargeable batteries may sometimes
drop so quickly that the unit will just shut down. The unit
will power down and restart. Just replace the batteries and
power the unit back on.
