When the battery has been installed, check that the battery housing and
O-ring are clean. The O-ring must always be lubricated with a thin layer of
silicone lubricant.
A screwdriver for GSMS/M101A assembling/
disassembling is provided in the com unit package.
If the GSMS or M101A are not going to be used for a while, the
battery should be removed. The cap must be stored into the battery
compartment (figure 11). This will ensure that the unit will work properly for a
longer period of time.

CHECKING BEFORE USE
GSMs and M-101A
Once the battery has been installed and you have checked that the cap and
cover have been closed properly, dampen your fingers and touch the two
screws (On/Off switch contacts) and activate the polarity circuit. You will hear
a “beep” indicating activation.
Run another finger along the antenna. You will hear a “zzzzzz” type sound
coming from the speaker.
Try to bring the antenna transducer near the antenna on a Digital M105 unit,
or the antenna on a GSMs unit (about 5 cm / 2 inches), keeping your fingers
on the On/Off contacts. You should also be able to hear the communication
when the unit is not immersed in water.
If you hear a repeated “beep” (about every 30 seconds) this means that the
battery is running low. Change it.
