Typically it takes a second or more to send a page to a pager. If the page is intended for a group of
pagers, it may take longer. A group consisting of 10 pagers may take 5-10 seconds to transmit, and a
group of 100 pagers may take 50-100 seconds to transmit.
2.6 Group Page
The OSMAC Base can send a page to a group of pager numbers through the entry of a single group
number. The pager numbers that are members of the group must have been previously assigned using
the Assign Group configuration menu. When sending a group page, the OSMAC Base sequentially
sends the page to each pager in the group.
The procedure for sending a group page is the same as for the individual page described in the above
procedure. Group pages generally take longer to send out, so you may find the OSMAC Base will take a
bit longer to return to the
PAGER NO= prompt when a group page is sent.
2.7 Tone Paging to Alphanumeric or Numeric Pagers
Some pagers can receive tone or numeric pages. If you wish to send a tone page (make it beep) to a
POCSAG pager that is set-up for numeric or alpha paging, you can press the F4 (Tone) key when
entering the page instead of the F1 (Enter) key. Pressing the F4 key after entering the pager number will
force the OSMAC Base to send a tone page to the pager.
2.8 2-way voice communications
The OSMAC Base can communicate with portable and mobile two-way radios. The OSMAC Base has a
privacy feature called Continuous Tone Coded Squelch System (CTCSS). CTCSS blocks the reception of
signals or noise that are not encoded with certain preset low frequency tones. You will only hear signals
at the OSMAC Base that have the correct CTCSS tone encoded on them. This means that the radio
channel may be in use by someone else, and you will not hear anything come out the speaker because
the CTCSS decoder has muted it.
To disable the CTCSS decoder momentarily in order to monitor all of the communications on the channel,
press the F2 key on the built-in keypad.
To talk on the radio channel, press and hold down the F3 key on the built-in keypad. If the channel is not
in use, the OSMAC Base will turn the transmitter on and display TALK on the LCD. Your voice will be
transmitted out over the air. The microphone is located on the front of the unit, so speak clearly towards it
in a normal voice.
2.9 Alarm Pages
The OSMAC Base has 8 alarm inputs located at the rear of the unit. The unit may be configured to send
a page when an alarm input changes states. Different messages may be sent for high or low going
changes of state.
For convenience sending pre-programmed messages, alarm pages may also be initiated from the
external keyboard. Low change alarm messages may be generated by pressing CTRL and a number key
"n" simultaneously, where "n" is the desired alarm number. High change alarm messages may be
generated by pressing CTRL, SHIFT and the number key simultaneously.
If no message has been programmed for a specific alarm page state, then no page will be sent. This
feature may be used to only send pages for a specific state transition, but not for the opposite state
transition.
