18 98540_UM_ AIR_ D
3.5.1 When to change battery
Replace the battery before expiry date. The battery pack, X-80242, has a shelf
life of 4 years.
If Tron AIR is indicating low voltage during a regular test procedure, also
change the battery. The TX LED also flashes when battery voltage is low.
3.5.2 Special care
The battery pack, X-80242, is of high-energy lithium type, and some
precautions must be taken.
Do not heat above 70oC, 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.
To prevent the possibility of being in an emergency situation with a Tron
AIR equipped with a used battery, we strongly recommend storing an extra
battery, in lifeboats and rafts. Store this battery without breaking the
sealing. Secondary battery and charger
3.5.3 Using the Nickel-Cadmium (NiCad) Battery
Tron AIR 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 changing the batteries, see chapter 3.4 how to change the battery.
98540_UM_ AIR_ D 19
3.5.4 How to Charge the NiCad Battery
1. Use the Tron CHARGE NiCad charger and power it up.
2. The power of Tron AIR must be switch OFF, or remove the battery
unit from the transceiver.
3. Insert the Tron AIR / 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.
6. Charge temperature must be between 0ºC and 40ºC.
7. After charging, remove the unit from the charger. The Tron AIR
and battery is now ready for operation.
3.5.5 Special care
The battery pack, 93003 and 93030, is of Nickel-Cadmium type, and some
precautions must be taken.
Do not short-circuit, 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.
20 98540_UM_ AIR_ D
3.5.6 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 80242.
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 230VAC, 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.

6 MAINTENANCE AND TROUBLESHOOTING
6.1 How to take care of your Tron AIR
Tron AIR is constructed to endure the rough maritime environment. Still the life
is dependent on taking care of the equipment. It is a good practice to regularly
inspect and test the equipment to trace error symptoms and prevent more
serious problems.
To keep in mind during inspection:
- If Tron AIR has been immersed into sea water, it is good
practice to clean it in fresh water.
- Inspect battery sealing and battery gasket.
- Inspect the housing for defects, which can affect the water
sealing.
6.2 Regular test procedure
It is important to perform regularly testing to ensure proper operation in case of
a distress situation. If Tron AIR is used regularly, perform test every month.
When Tron AIR is stored in a lifeboat or raft, perform test at least once a year.

7 PRACTICAL USE, VHF TRANSMISSION RANGE
The range of VHF communications is limited to ‘line of sight’, because the
VHF radio waves are travelling in straight lines. A higher position of the
transceiver will then increase the coverage. This applies both to the receiving
and transmitting end.
Some figures are indicated in the table below:
1 Nautical mile = 1852 Meters = 1.1508 Miles
1 Statute mile = 1.609 Kilometres
This indicates that with a handheld VHF, used at sea level, the range will be
approx 8 Km (5 Miles). The range will increase if the height above sea level
increases, and also if the other user in the other end is at a higher level.
