User Guide
All batteries can cause property damage and/or bodily injury such as burns
if a conductive material such as jewelry, keys or beaded chains touches
exposed terminals. The material may complete an electrical circuit (short
circuit) and become quite hot. Exercise care in handling any charged battery,
particularly when placing it inside a pocket, purse or other container with
metal objects.
Do not replace or charge batteries in potentially explosive atmosphere.
Contact sparking may occurwhile installing or removing batteries and cause
an explosion.
Due to the risk of electrical shock or other physical injury, never insert your
hands into the charger pocket.
Warning For Vehicles Equipped With an Airbag
An airbag inflates with great force. DO NOT place objects, including
communication equipment, in the area over the airbag or in the airbag deployment
area. If the communication equipment is improperly installed and the airbag
inflates, this could cause serious injury.
•Installation of vehicle communication equipment should be performed by a
professional installer/technician qualified in the requirements for such
installations. An airbag’s size, shape, and deployment area can vary by
vehicle make, model, and front compartment configuration (e.g., bench seat
vs. bucket seats).
•Contact the vehicle manufacturer’s corporate headquarters, if necessary, for
specific airbag information for the vehicle make, model, and front
compartment configuration involved in your communication equipment
installation.
Important Note: If a vehicular repeater is installed, verify operation of the repeater before
leaving the vicinity of the vehicle.

About the Vehicular Charger
The NTN9176_ Tri-Chemistry Vehicular Charger is a 12Vdc vehicular charger for the following
nickel-cadmium (NiCd), nickel-metal-hydride (NiMH), and lithium-ion (Li-Ion) batteries for
XTS 2500, XTS 1500, MT 1500, XTS 3000, XTS 3500 and XTS 5000 series portable radios:
The charger uses a microprocessor to sense the type of battery inserted and control the rate of
charge accordingly. A battery will be charged at a rapid rate until it is fully charged, then the
charger will switch to a trickle charge mode to keep the battery fully charged.
The charger can charge either a battery that is attached to a radio or just the battery alone. This
allows a spare battery to be maintained in a fully charged condition.
A radio can be operated while in the charger, but this will prolong the amount of time needed to
fully charge the battery.
NOTE: Excessive use of a radio while it is in the charger will cause its battery to become
discharged.

Securing the Radio in the Vehicular Charger
The NTN9176_ Vehicular Charger is equipped with a feature that reduces the risk of a portable
radio (or battery alone) in the pocket from becoming dislodged and potentially hazardous in the
event of a vehicular collision. Operators are instructed to follow the vehicular charger
installation instructions and to use this feature as follows:
1. Anyone intending to operate the vehicular charger is advised to locate and become
familiar with:
• the stationary leather strap that protrudes from the lower edge of the pocket opening,
• the cord, and
• the snappable leather latch.
The buttons on the latch and housing top are designed to mate with the snap on the strap.
2. When the vehicular charger is not in use, the latch may be snapped to the strap to stow it.
The unit is shipped from the factory in this configuration.
3. To use the vehicular charger, insert the portable radio or battery alone into the charger
pocket.
4. Unsnap the leather latch from the strap.
5. For radios with an antenna installed, loop the cord around the base of the antenna and then
snap the latch back onto the strap (refer to Figure 1).

Operating the Vehicular Charger
Never place any objects other than a radio and/or battery into the charger
pocket — this could damage the charger!
NOTE: For best charging results, turn the portable radio off while it is in the vehicular charger.
Leaving the radio on will significantly increase the amount of time required to
recharge the battery.
Operation of the charger is automatic. When a portable radio or a battery is not in the charger’s
pocket, the charger is in standby mode.
To charge a battery, place the radio and battery (or battery alone) into the pocket and push all the
way down. While pushing the radio into the pocket, take care not to inadvertently activate the
radio’s emergency button.
If a battery aloneis placed in the charger, be sure that theslots on either side ofthe battery engage
the two metal tabs at thebottom of the pocket, near the four gold-plated charger terminals. When
the battery is properly seated inthe charger pocket, the red LED willlight steadily. This indicates
that the battery is being charged in the rapid-charge mode.
Also, if the radio and battery are in the charger pocket, loop the safety strap around the radio
antenna, as shown in figures 1 and 2. If a battery alone is in the pocket, pass the safety strap over
the top end of the battery and snap it securely to the snap fitting on the topof the charger housing,
as shown in Figure 3. This will prevent the battery from being shaken out of the charger during
rough traveling conditions, and will also prevent it from becoming a dangerous projectile in the
event of a vehicle crash.

Specifications
Installation
Mounting hardware supplied includes atrunnion bracket for mounting the unit below the vehicle
dashboard, on the floor, or on the wall, and a cable for connection to the vehicle’s electrical
system. The bracket enables the charger to be pivoted to a position that offers the best security
to the portable radio during rough driving conditions.
Install the vehicular charger as follows:
1. Plan the location for mounting the charger. Identify the routing paths for the cable and verify
that the cable length is adequate. Also check the mounting penetrations required. On most
vehicles, it is necessary to penetrate the firewall to reach the battery. Check the opposite side of
the firewall for cable clearance before drilling holes. Protect the cable where it passes through
the firewall by use of appropriate rubber grommets (notsupplied) or other protective measures.
Survey the firewall for existing holes occupied by vehicle wire harnesses. Often there is an
opportunity to route other cables using the same path. Because of the wide variation in
vehicle design, these instructions may be modified to suit each particular installation.
A properly installed unit will minimize service calls and equipment downtime. Consider
the following guidelines when planning the installation:
• DO consider a mounting location which will allowthe unit to be mounted at a 45-degree
up angle. This angle provides operational convenience and physical security for the
portable radio under rough traveling conditions.
• DO use heat shrink tubing on all splices.

• DO ensure that the cable is not placed under stress, is not exposed to weather, and is
not subjected to damage due to engine heat.
• DO retain the in-line cable fuse when trimming the cable to fit. Locate the in-line fuse
as close as practical to the supply voltage connection.
• DO check the opposite sides of all mounting surfaces before drilling, to insure that
there are no obstructions, such as vehicle wiring and fluid lines.
• DON’T attach the unit to any part of the vehicle that is not rigid or is subject to
excessive vibration.
• DON’T install the unit in an area where rain or snow can easily get into it, such as next
to a vehicle window which may be left open.
• DON’Tinstall the unit in a location where itcould interfere with the vehicle’s operator
or operating controls.
• DON’T dress the cable over sharp edges that could cause wear or tearing of cable
insulation.
• DON’T install the unit in a location where it may be difficult for the operator to reach.
• DON’T install the unit where it may interfere with the vehicle safety air bag
deployment.
• DON’T install the unit where the LED indicators and switch may become physically
damaged.
2. Using the trunnion bracket as a template, mark the mounting surface drilling locations. It
is recommended that at least four screws be used, with 1/4 inch being the preferred
fastener diameter.
3. Re-verify that there are no wires, fluid lines, or other obstructions on the other side of the
mounting location, and drill appropriate sized holes for the mounting screws to be used.
4. Referring to Figure 4, mount the bracket using appropriate screws, washers, lock washers,
and nuts.
5. Insert the unit into the bracket, and install the threaded knobs into the housing, as shown.
