DEPTH 3100 Manual de Instalação e OperaçõesNAVMAN
Set backlight for screen and keys
You can set the backlight to one of four brightness
levels or off. Press once to display the current
backlight level, press again to change the level:
The display normally shows depth. If it displays
dashes (— —) then it means that the depth is too
deep or unknown.
The DEPTH 3100 can be set to sound an alarm when
the water is too deep or too shallow (see sections 3-
2 and 3-3). When the alarm sounds, the internal
beeper sounds, the symbol on the display flashes
and any external beepers or lights operate.
Press to mute the alarm. The alarm stays muted
until the depth becomes normal. The alarm will sound
if the depth becomes too deep or too shallow again.
2-4 Simulate mode
Simulate mode allows you to become familiar with
the unit off the water. In Simulate mode, the DEPTH
3100 functions normally except the transducer is
ignored and the unit generates this data internally.
The word SIMULATE flashes at the top, left corner
of the screen.
To turn Simulate mode on or off:
1 Turn the power off.
2 Hold down while you turn the power on.
