CAUTION
When replacing the batteries, be sure to replace
the two batteries at the same time and do not
use an old and a new battery together.
■ Disassembling
1) Loosen the two battery case mounting screws
(Figure 9.5).
2) Separate the battery case into two parts.
3) Remove the old batteries.
■ Assembling
1) Insert new batteries into the battery case. Be
careful of the orientation of the batteries.
2) Attach the two parts of the battery case to each
other.
3) Tighten the two battery case mounting screws
to a torque of approximately 0.7 N·m.

9.4.7 Handling Batteries
This battery pack uses two primary lithium/
thionyl chloride batteries. Each battery contains
approximately 5 grams of lithium, for a total of 10
grams in each pack. Under normal conditions,
the battery materials are self-contained and are
not reactive as long as the batteries and the pack
integrity are maintained. Care should be taken to
prevent thermal, electrical or mechanical damage.
Protect the electrode of the battery pack to avoid
rapid electrical discharge. Discharged a battery may
lead to fluid leakage and excessive heat. Batteries
should be stored in a clean and dry area. For
maximum battery life, storage temperature should
not exceed 30°C.
WARNING
Handling the battery pack
The following precautions must be observed
in order to safely and effectively use a battery
pack. Improper use may lead to fluid leakage,
excessive heat, ignition, or explosion.
• Never charge it.
• Do not short-circuit it.
• Do not disassemble, transform, or modify it.
• Do not heat it or throw it into a fire.
• Do not soak it in fresh water or seawater.
CAUTION
Observe the following precautions for the safe
disposal of batteries.
• Do not incinerate the battery, and do not
expose it to a high temperature of 100°C
or more. This may lead to fluid leakage or
explosion.
• Dispose of the battery according to laws and
regulations.
Use the following dedicated parts for the battery
pack and batteries.
■ Battery Pack
Part number: F9915NQ (with batteries)
Part number: F9915NK (without batteries)
■ Batteries
Part number: F9915NR
Alternatively, Tadiran TL-5930/S batteries may
be purchased and used.
■ Transportation of products containing
lithium batteries:
Batteries used for this transmitter contain
lithium. Primary lithium batteries are regulated
in transportation by the U.S. Department of
Transportation, and are also covered by the
International Air Transport Association (IATA), the
International Civil Aviation Organization (ICAO), and
the European Ground Transportation of Dangerous
Goods (ARD). It is the responsibility of the shipper
to ensure compliance with these or any other local
requirements. Consult current regulations and
