your system administrator, you also hear your ringtone play. The ringtone plays

according to the following schedule:

 At 10 minutes before power off, the ringtone plays four times

 At 7 minutes before power off, the ringtone plays four times

 At 4 minutes before power off, the ringtone plays four times

 At 30 seconds before power off, the ring tone plays 15 times or until the

phone powers off

If your phone is inactive (idle) at the sleep time, you see a message to remind you

that your phone is about to power down. To keep the phone active, you need to

press OK in the message or any key on the phone. If you do not press the button or

any key, your phone powers down.

If your phone is active (for example, on a call), your phone waits until it has been

inactive for a period of time before telling you of the pending power shutdown. Before

the shutdown happens, you see a message to remind you that your phone is about

to power off.

After your phone goes to sleep, press Select to wake up your phone. After the phone

is inactive for a period of time, a message displays to alert you that the phone is

about to power down. At the configured wake time, your phone powers up.

Wake and sleep times are also linked to the configured days that you normally work.

If your requirements change (for example, your work hours or work days change),

contact your system administrator to have your phone reconfigured.

Clean Phone Display

When the phone is in sleep mode, the touchscreen is blank and the Select button is

not lit. When the phone is in this condition, you can clean the screen, as long as you

know that the phone will remain asleep until after you finish cleaning. If the phone is

likely to wake up during cleaning, wake it up or wait until it is awake before following

the preceding cleaning instructions.

Caution! Use only a soft, dry cloth to wipe the phone display. Do not use any liquids

or powders on the phone because they can contaminate phone components and

cause failures.

Step 1: Before cleaning the phone display, press Select until you see the message

Touchscreen Disabled to disable the phone screen.

The phone screen re-enables automatically after 60 seconds.

Step 2 To re-enable the phone screen manually after cleaning, press Select until

you see the message Touchscreen Enabled.

Call History

Call History allows you to view information about the last 150 calls on your phone.

The Call History lists individual calls. If your phone has multiple lines, calls on all

lines are added together. The oldest calls over the 150-call limit are dropped from the

history.

If the caller ID is unavailable, “Unknown” is displayed, and the phone number is

listed.
