3. Installation 3-1 Installing a Battery Pack ➀ ➁ Insert the saw-toothed end on the bottom of the battery into the slots on the bottom of the phone (➀), then slide the battery down (➁). ➂ ➀ ➁ Push up and hold the catch above the battery on the back of the phone (➀) and lift the battery away.
Installation 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.
Installation 3-3 For Mobile Mount 3-3-1 Cradle 1. Choose a location where it is easy to reach and does not interfere with the driver’s 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.
Installation 3-3-3 Hands-Free Microphone 1. It is recommended to install the microphone where it is 30-45 cm (12-18inch 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 3-3-4 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 the power cable as follows: Connect the red wire to the battery (+) terminal, black wire to the vehicle chassis. Then connect the battery (-) terminal to the vehicle chassis. Connect the yellow wire to the switched side of the ignition switch, and then connect the white to the stereo mute wire from your vehicle stereo. 4.
4. NAM Programming NAM features can be programmed as follows: Notes: - If you enter the NAM program mode, each item shows the currenly stored data.
