– Leather / nylon case

– Carrying chain / bungee cord

– Desktop charging cradle, Rod Antenna, Alert Siren

– Data cradle (Adapter with serial data interface)

– Programming kit (Adapter and PC Software)

RE-ROUTING RECEIVED MESSAGES

After choosing the Message route symbol · in the function menu you can re-route

any received message to a PC, printer or large size display via optional data cradle

(desktop pager adapter with serial data interface).

PAGER DEACTIVATED FUNCTION

In case your pager displays PAGER PROTECT then it cannot receive messages

any longer because it was set to a remote maintenance condition by the paging sys-

tem’s transmitter ”over the air”.

LOW BATTERY ALERT

When the battery voltage drops, the symbol 9 (battery warning level 1) is dis-

played. Whenever the symbol = (battery warning level 2) is displayed, the battery

must be charged or replaced to the fully charged one very soon (backlight turns off

automatically).

When the battery voltage reaches one of the warning levels the pager emits a low

battery alert. If you do not recognize the alert (you do not press any button) there will

be a repetition in regular intervals and the symbol 9 or = flashes.

BATTERY REPLACEMENT

To install or replace the battery, place the pager face down, then:

1. Unlock the battery cover by sliding

the cover latch up with your thumb.

2. Slide the battery cover to the right.

3. Remove the battery cover.

4. Install the battery.

5. Close the battery compartment cover.

PAGER LX4

USER MANUAL

19 / 25

Important notes:

– Take care to ensure correct polarity of the battery (see polarity markings next to

the battery cover).

– All received messages remain stored during a battery change.

– Do not use carbon zinc batteries.

CHARGING / SELECTING CELL TYPE

A regular charging the battery is necessary.

Important Notice: Do not try to charge non-chargeable batteries as there is the

risk of the battery explosion!

After a battery replacement pager displays (with an audible alert) a message to con-

firm the battery cell type (chargeable or non-chargeable battery). This is to prevent

unintentional charging of a non-chargeable battery. Select the proper cell type by

pressing the button ⁄ or Ÿ, and confirm your selection by pressing ◊ button.

Charging: For charging, open the cover frame of the desktop charger and put the

pager into the charger. Afterwards close the frame. After a short time, the symbol

6 is displayed. In case it does not display, please take off the pager and place it

carefully back again.

Note: Clean the charging contacts, regularly.

If the pager’s rechargeable battery is exhausted, it may happen that the charging is

not turned on automatically. In this case leave your pager inside the charger for some

minutes. Afterwards take it off and place it again in order to start the supervised

charging procedure.

The rechargeable battery is charged in a supervised way inside the Charging Unit,

i.e. it is charged as long as necessary, depending on the charging state. After the su-

pervised charging is done, the charger moves over to a trickle charge mode. This

procedure is to achieve the longest possible rechargeable battery life.

Note: Do not leave your pager inside the charger, permanently.

Important: To make possible the supervised charging procedure and reliable Low

Battery Alert function, it is necessary to set the nominal capacity of the rechargeable

battery during programming of the pager (refer to statements of the manufacturer, i.e.

2400mAh).

PAGER LX4

USER MANUAL

20 / 25

Note: If you want to use a new rechargeable battery, it has to be fully charged one

time, first. Otherwise the charging state is unknown and the charging procedure (de-

scribed above) cannot work. Therefore, the rechargeable battery should not be taken

out of the pager unnecessarily. Factory-new rechargeable batteries reach their maxi-

mum possible capacity after several cycles of charge and discharge, only.
