• Power On/Off Key – Powers SR-20 on.
• Up and Down Keys – Used for locating choices during
menu selection.
• Signal Focus – If activated, the Up and Down Keys
will change the Signal Focus setting up and down. A long
press (greater than ½ second) on these keys will adjust
the Proximity Threshold, while a quick press will adjust
the Signal Focus.
• Select Key – Used to make a choice during Menu
selection; in normal operation, to force a Measured Depth
reading and recenter audio tone.
• Menu Key – Used to display a “tree” of choices including
frequency selections, display element choices, brightness
and contrast, and restoring default settings. In a menu, will
move up one level.
• Volume Control Key – Used to raise or lower the volume
setting.
• Frequency Key – Used to set the In-Use Frequency of the
SR-20 from the set of Checked-Active frequencies. The list of
frequencies that have been set to Checked-Active status can
be modified via the Menu Key. Frequencies are grouped into
four sets: Sonde Frequencies (
), Line Trace Frequencies
( ), Power Frequencies ( ) and Radio Frequencies ( ).
Each press cycles to the next Checked-Active frequency.
• Light Sensor – In Automatic mode, the light sensor controls
when the backlight goes on or off depending on ambient
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 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 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.
