light.

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 aect 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 will periodically

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.
