Step 4. Optional Battery Installation

Your Phonecell SX3i has an internal power supply with battery backup that pro- vides uninterrupted talk time and standby operation in the event of AC power failure. The power supply will trickle-charge the batteries while AC power is available. However, no recharging occurs during conversation mode.

The FWT uses two 6-Volt (4.5 Amp. Hr.) batteries (not supplied). Batteries are not shipped in the unit to prevent damage and to avoid power draining. To install bat- teries, turn the Phonecell upside down and follow the instructions below:

DANGER!

Follow these instructions exactly. If the wire leads are not connected ! to the proper terminals, the circuit board and/or transceiver may be

damaged. Always observe proper polarity (make sure the colored wires match) while installing the wire leads and connecting wire.

1)Make sure that the switch is in the off position.

2)Disconnect AC and/or DC power cord(s).

3)Locate the battery compartment, which is next to the silver transceiver on the back of the FWT -- see Figure. 7.

NOTE: Make sure that the power switch is in the OFF position.

4)Remove the battery compartment cover by pressing the securing tab downward while sliding the lid toward the securing tab.

5)Position the Phonecell so that the battery compartment is closest to you and the sil- ver transceiver is furthest away from you.

	CAUTION!
!
	Do Not allow the battery terminals to touch the silver transceiver
	at any time, under any circumstances.

6)Place an insulator (i.e. paper or

plastic) between the batteries and silver transceiver -- as shown in Figure 8. This will prevent the batteries from damaging the Phonecell’s transceiver.
