Simrad PI Spread/Depth
CHARGING AND MAINTENANCE
This chapter explains how you shall recharge the battery in the PI
Spread/Depth sensor, and how you shall best maintain the sensor.
PI Spread/Depth maintenance
Once installed and put to use, the sensor will automatically be
switched on once the water switch is activated. After an initial
start-up, the sensor starts transmission of the current depth and
distance.
When the sensor is not in use, check that the sensor lamp is not
flashing, as this indicates that the sensor is active and discharging
its batteries. In this case, wash the sensor in fresh water.
All sensors are equipped with a water switch, and two different
types are used. If your sensor is equipped with a sacrificial brass
screw, observe the following procedure for replacement.
1
Turn the sensor upside down, and locate the brass screw.
2
Inspect the screw for wear and tear.
3
If replacement is required, locate a new screw.
Before a new screw is inserted,
Aqua Shield
(or a similar
underwater lubricant) must be applied. Due to the size of
the tube, we recommend that the grease is applied from
a syringe.
4
Apply
Aqua Shield
to the screw threads.
5
Insert the screw, mount firmly, but not too hard. Use
maximum torque 1.5 NM
A pack with ten screws and a tube of
Aqua Shield
can be
ordered from Simrad as a spare parts kit.
Aqua Shield
is manufactured by D.A.Stuart, Warrenville,
Illinois, USA.

serviceable parts inside, and you may easily cause a leak.
