3-1 Installing a Battery Pack
Figure 3-1 Charging the Phone and Battery
1. To attach the battery pack after charging, align it
with the phone about 1cm (1/2Ó) away from its
place so that the two arrows on the phone are
seen, the battery charge contacts pointing
downward.
2. Slide the battery pack upwards until it clicks
firmly into position. The phone is now ready to
be turned on.
3. To remove the battery pack, release it by
pressing the button on the rear of the phone.
4. Slide the battery pack downward about 1cm
(1/2Ó) and lift it away from the phone.
3-2 For Desk Top Use
1. Choose a proper location to install the charger
for desk top use.
2. Plug the power cord of the charger into an
appropriate wall socket. When the power is
connected correctly, the lamps turn on briefly.
3. To charge the battery pack, insert the battery
pack into the rear slot of the charger. The lamp
marked BAT on the front panel of the charger
lights up red.
4. If you do not wish to use the phone while
charging the battery, insert the phone with the
battery pack attached into the front slot of the
charger. The lamp marked PHONE on the front
panel of the charger lights up red.

3-3 For Mobile Mount
3-3-1 Antenna
1. Choose a proper location to install the antenna.
¥The center of the roof top provides the best
performance.
¥The edge of the rear trunk also provides a
good performance. However, the antenna
should be higher than the roof of the car.
¥In case of on-glass antenna, you should align
the antenna base with the round plate to
connect the cables correctly.
2. Mount the antenna vertically, connect the
antenna cable.
3. Tighten the antenna nut fully.
3-3-2 Cradle
1. Choose a location where it is easy to reach and
does not interfere with the driverÕs safe
operation of the car.
2. Separate the two halves of the clamshell by
removing the two large slotted screws. See the
figure 3-2.
3. Drill holes and mount the lower half of the
clamshell by using the screws.
4. Place the cradle onto the remaining half of the
clamshell and assemble them by using the
screws.
5. Reassemble the two halves of the clamshell
together. Adjust the mounting angle and tighten
the two slotted screws.

1. Drill holes in a proper location for the hands-
free box, attach the mounting bracket by using
the screws. See the figure 3-3.
2. Install the hands-free box into the bracket.
3-3-4 Hands-Free Microphone
1. It is recommended to install the microphone
where it is 30-45 cm (12-18Ó) away from the
driver. Choose the location where is least
susceptible to interference caused by external
noise sources, ie, adjacent windows, radio
speakers, etc. Normal place is the sun visor.
2. Once the microphone has been correctly
positioned, connect the microphone wire to the
MIC jack on the hands-free box.

Installation
3-3-5 Cables
1. Connect the cradle and the hands-free box with
the data cable. See the figure 3-4.
2. Connect the antenna cable to the RF jack of the
cradle.
3. Connect one of the power cable to the battery or
ignition terminal. Connect the red wire to the
battery (+) terminal, black wire to the vehicle
chassis. Then connect the battery (-) terminal to
the vehicle chassis.
4. Connect the other end of the power cable to the
PWR jack of the hands-free box.
Notes:
¥It is recommended to connect the power cable
directly to the battery to avoid power noise.
¥Make sure the connection between the battery (-)
terminal and vehicle chassis is made correctly.
¥Make sure the fuse having a proper capacity is
used on the power cable.
¥Make sure the cables do not pass over any sharp
metal edge that may damage it.
