The ZQ-5000/5200 is equipped with the following two circuits for low battery detection:

Main battery voltage detection circuit Memory protection battery voltage detection circuit

The main battery voltage detection circuit

detects the battery voltage during operation of the unit. When the voltage falls to the caution level (about 4.4 to 4.8V), the LCD battery lamp lights up. When the voltage falls to the fatal level (about 3.9 to 4.2V), the power is compul- sority turned off. This operation is common with the OZ/IQ-7000.

All detection circuit detect the battery voltage when the power is turned on, and provide the message of low battery if required.

The detection procedures in that case are as follows:

The fatal level of the battery for operating the unit is checked. (If

If the batteries become weaker, the power may go off during operation. The memory contents will still be retained by the memory backup battery. Replace the operating batteries to avoid

loss or alteration of data. Do not remove both the operating and memory backup batteries at the same time. All the data stored in the memory will be lost. Before removing the batteries for replacement, jot down the important data stored in the Organizer in hard copy form.

Always replace both operating batteries at the same time. Do not use an old battery and a new one together. Use only the specified lithium batteries. Replace the memory backup battery at least every

years, or when

Battery replacement

For example, if you replace the battery in December, 1996, write:

Set the battery replacement switch to “Replace OPERATING batteries”.

Slide out the battery holder and remove the old batteries from the battery compartment using a bail-point pen or similar object. (Be sure to keep the memory backup battery installed while doing this.)

Clean the new batteries carefully with a dry cloth, then insert them, making sure that the

side faces up. Slide the battery holder back into place. Set the battery replacement switch back to “Normal Operation”.

If the battery replacement switch is not set to “Normal Operation”,

the Organizer will not operate properly. Replace the rear cover. Press

to turn the power on. If the power is not turned on or a meaningless display appears, press the. RESET switch on the back. If the Organizer still does not operate properly, repeat the battery replacement procedure from the beginning.

battery

The memory backup battery in your Organizer has an effective life of about

years under normal operating conditions. Note that temperature extremes can shorten the battery life and cause memory losses. The memory backup battery was installed at the factory.

Replace the memory backup battery every 5 years, or when the

message appears.

Extremes of temperature will shorten battery life and endanger the memory information.

When replacing the memory backup battery, make sure that the rating batteries are not depleted. If the operating batteries are depleted, replace these before replacing the memory backup battery. If you replace the memory backup battery while the operating battery is depleted, all of the data in the memory will be lost.

Press

to turn the power off. Press the rear cover and slide to remove it. Set the battery replacement switch to “Replace MEMORY backup

battery”. Slide out the battery holder, then remove the old battery from the

battery compartment using a bail-point pen or similar object. (At this time, make sure that you keep the operating batteries installed.)

Data communications between two Organizers

This function is used to transfer data in the memory of one Organizer

to another Organizer, such as the IQ-7000 or ZQ-Series Organizer.

The optional data transfer cable, CE-200UCE-300L, is required for this transfer.

Data transfer can be performed for data in the

mode.

Data cannot be transferred from the Anniversary mode or the User Dictionary mode.

To transfer data to an EL-Series Organizer or Auto Dialer featuring data transfer, use the optional data transfer cable CE-220T for connection.

For example, data in the telephone directory can be transferred.

If the second Organizer does not support the mode from

which data in the first Organizer is to be transferred, data transfer will not be performed. For example, if the IQ-701A card is not installed in the IQ-7000, the data from the DO LIST or EXPENSE mode will not be transferred.

1. Turn the power off on both units.

Push the covers up to reveal the 4-pin option jack of both units.

Connect the data transfer cable to the 4-pin option jacks.

The cable connector is equipped with a projection (guide key) to

indicate its connection position. When connecting it to the 4-pin option

jack, make sure the guide key is always positioned to the

Improper connection may cause the data stored in the Organizer to

be lost.
