The options of the first line of this screen are IN, OUT,
BOTH, or OFF. IN calls are from a remote terminal
operator to the UPS. OUT calls are alarms reported from
the UPS to a selected phone number with a modem
attached. BOTH enables both IN and OUT calls. OFF
disables modem connections, but a directly connected
computer terminal may still be used.
The second line allows entry of the phone number the
UPS calls when alarms occur. Remember to include a 9

UPS makes up to 3 attempts to connect, spaced 45 to 90
seconds apart, before giving up.

For UPS OUT calls, the receiving terminal beeps and
displays the message ”Press any key to enter terminal
mode...”. If no key is pressed within 10 seconds, the
terminal displays present alarm condition(s) information

the message ”Press any key to enter terminal mode...”
displays again. Press a key to enter terminal mode, and
show the LCD display as described earlier in Terminal
Operation. If no keys are pressed for 45 seconds, the
UPS hangs up.
