5 INSTALLATION AND OPERATION
5.1
OPERATION
The 2830A comes in a yellow, rugged plastic case. To open the enclosure: release the two
latches on the front of the unit and raise the lid. The lid of the communicator can be removed
by sliding the lid to the side.
The AMCOM III panels are graphically dived into sections: Tender Controls, Diver Controls,
and Power input. Items within these areas are functions or controls relating to the Tender,
Diver(s) or power items.
5.2
CHARGING THE BATTERY
The AMCOM III portable diver communicators are supplied with a gel cell sealed lead acid
battery, with an internal charger. To charge the batteries, connect the unit to a 110/220 V
AC
outlet. The charger has an universal input voltage range of 90-264V
RMS
with a frequency
range of 47-440Hz. Always use a power cord approved for the country of use. It may be
purchased locally or ordered from AMRON.
It is recommended the unit be placed on charge, and left on charge, until the unit is to be
used again. This ensures the unit will always be ready to use, and the batteries are fully
charged. The charger is designed not to damage the batteries when left on continuous
charge. Full charge will occur in roughly 10 hours (depending on the age of the battery and
the surrounding temperature). If the unit is in constant use (daily) it is recommended the unit
be left on charge during the weekend to top off the batteries. Batteries must be recharged
periodically, a minimum of at least once every six months.
Operating time for the rechargeable batteries depends upon the age of the batteries. Gel Cell
batteries have a life of 300 cycles, or 3 years. Gel cell batteries do not have memory;
therefore they can be placed on charge at any time.
NOTE
: Do not continue to operate rechargeable batteries below the low battery condition or
permanent damage will occur. When the battery condition indicator turns to red color, shut
unit off and charge batteries.
5.3
INITIAL POWER ON - BATTERY CONDITION CHECK
Turn all the volume controls to minimum and turn on the POWER SWITCH. The state of the
battery is shown on the BATTERY CONDITION INDICATOR as follows:
STEADY GREEN
–
the battery is good and has more than 30% remaining life
BLINKING GREEN
–
the battery is low and has less than 30% remaining life
OFF or NO LIGHT the battery is depleted and needs to be changed/recharged before
use
The BLINKING GREEN light provides a warning that the battery is low and should be
changed or recharged before starting the dive operation. When the indicator starts BLINKING
GREEN during dive operations, there is, depending on age of the battery and the ambient
temperature, approximately 4 hours of remaining life for the 2830A. This should be sufficient
