TEST OF RADIO EQUIPMENT AND RESERVE SOURCE OF ENERGY

Weekly:

GMDSS handheld VHF transceivers to be tested without using the mandatory
required emergency batteries.

Monthly:

Float-free and manual EPIRBs to be checked using the means provided for testing on the
equipment. Check data for periodical maintenance requirement for float-free EPIRB.

Float-free EPIRBs are required to go through a periodical maintenance
every 24 months. (Only for NOR/NIS flag vessels).

False alerts transmitted by EPIRB

False alerts are a serious problem for the rescue service. Nearly 90% of EPIRB
initiated distress alerts turn out to be false alarms.

If for any reason, your EPIRB should cause a false alarm, it is most important that you
contact the nearest search and rescue authority and tell them it was a false alarm. They
can then stand down any rescue service (coast radio station or appropriate CES or
RCC). Use any means at your disposal to make contact. Switch off the distress alarm
by de-activating your EPIRB, as soon as possible.

3 PRIMARY BATTERY

3.1 HOW TO CHANGE THE BATTERY

The primary battery unit is a 7.2V / 5000mAh lithium cell.This unit is specially
designed for GMDSS emergency use to preserve a long shelf- and operating-life.
Type no. of battery: X-93002

Battery change procedure:

1) Hold down the two push-buttons on each side, and pull the battery pack
out of the housing.

2) Check the gasket inside the housing for no damage.
If it is broken, replace it with a new (stock no. X-93024). Remove dirt when
replacing the gasket.

3) Replace the expired battery.The label on the battery is marked with date
of replacement.
The primary battery is equipped with a seal to prevent inadvertent use.
Break this seal before use. Breaking this seal indicates that the shelf life has
expired.

4) Push the new battery unit into the housing until you hear the two push­buttons are clicking into right position.Tron VHF will not be waterproof
unless the pushbuttons are in correct position.

3.2 WHEN TO CHANGE THE BATTERY

Replace the battery before expiry date.The battery pack, 93002, has a shelf life
of 4 years.

If TronVHF is indicating low voltage during a regular test procedure, also change the
battery.The Tx LED also flashes when battery voltage is low.

To prevent the possibility of being in an emergency situation with a TronVHF
equipped with a used battery,we strongly recommend storing an extra battery-set,
93002, in lifeboats and rafts. Store this battery without breaking the plastic bag
sealing.

3.3 SPECIAL CARE

The battery pack, 93002, is of high energy lithium type, and some precautions
must be taken.
Do not heat above 100ºC, recharge, crush, disassemble or incinerate.This may
result in fire, explosion and severe burn hazard.
Do not throw used batteries overboard, but return them to your local dealer.

4 SECONDARY BATTERY AND CHARGER

4.1 USING THE NICKEL-CADMIUM BATTERY

Tron VHF can be delivered with a rechargeable NiCad battery,type
93003/93030 (850mAh/400mAh) which is equipped with two connectors
for charging with Tron CHARGE.
These battery are specially designed for On-Board communication.
After recharging the battery, it can be used in the same way as the primary
battery unit. However, the voltage of Nickel-Cadmium batteries drops rapidly
just before they are exhausted, so when the transmit indicator LED (Tx) goes
out, be sure to immediately stop using it, and recharge the batteries again.

When changeing the batteries, see chapter 3.1 How to change the battery.

4.2 HOW TO CHARGE THE NICKEL-CADMIUM BATTERY

1. Use the Tron CHARGE NiCad charger and power it up.

2. The power of Tron VHF must be switch OFF, or remove the battery
unit from the transceiver.

3. Insert the Tron VHF / battery unit into the charging slot.

4. The Charge LED will indicate that the charge cycle is beginning.
It is now operating in fast charge mode which will fully charge the
battery within 4 hours.

5. When Charge LED goes out, the battery is recharged.The charger
has now switched to trickle charge mode.

17

18

6. Charge temperature must be between 0ºC and 40ºC.

7. After charging, remove the unit from the charger.The Tron VHF and battery
is now ready for operation.

4.3 SPECIAL CARE

The battery pack, 93003 and 93030, is of Nickel-Cadmium type, and some precau­tions must be taken.
Do not shortcircuit, solder, reverse charge, crush, disassemble or incinerate.This may
result in fire, explosion and severe burn hazard.
Also avoid charging under 0ºC or over 40°C.

4.4 THE TRON CHARGE NICAD CHARGER

The Tron CHARGE NiCad charger is specially made for charging your secondary
battery,type 93003 or 93030. On the left side there is space for storing the primary
emergency battery,type 93002.
The charger has a fast charge facility which fully charges the 93003 battery within 4
hours.When the battery is fully charged, this is detected, and Tron CHARGE swit­ches to trickle charge mode.This is indicated with the
Charge LED switching off.
There are also built in temperature sensors detecting charge temperature limits and
sudden rises in battery temperature. If the charger is detecting out of limit tempera­tures, this causes the unit to switch to trickle charge mode. It is important to note
that the absolute battery temperature is not detected by the charger, and must be
within 0ºC to 40ºC when starting the charge cycle.The charger supply can be 230V
AC, 115V AC, 12 to 16V DC or 24 to 28V DC. For changing the AC source, modifi­cations must be done on the Printed Circuit Board.If a DC source is required, the
power cable must be connected to the +12VDC socket within the unit. For 24 to
28V DC an extra resistor of 33ohm/20W must be connected in serial with the
power supply.This resistor is available from JOTRON at stock number X-93750.

NOTE!

If Tron CHARGE is connected to a DC source with higher voltage than 16V DC, an
extra resistor of 33ohm/20W must be connected in serial with the power supply.
This resistor is available from JOTRON at stock number X-93750.
