2.4 Display
There is a two-line, twenty-character LCD display on the OSMAC BaseOSMAC Base. The three LEDs on the top right side of
the unit indicate the state of the transmitter, whether the channel is busy, and the programming mode.
2.5 Sending a page
The OSMAC BaseOSMAC Base is ready to send a page when the LCD display shows:
This means the OSMAC BaseOSMAC Base is waiting for you to enter the pager number to which you which to send a page.
Using the keypad or an external keyboard, enter the number (not the CAP code) of the pager you wish to page.
Once you enter the pager number, press the F1 key. There are three standard types of pagers supported by the
OSMAC BaseOSMAC Base. They are: tone-only, numeric and alpha-numeric. An option is available which supports two-tone
pagers as well. Depending upon what type of pager you are sending the page to, one of the following sequences
will take place:
1. POCSAG tone-only pagers
If the pager is a tone-only type, it does not have a display. A page sent to it will cause it to beep.
When a page is sent to it, the display will show TONE PAGER TONE PAGER while it is sending the page over-the-air to the
pager. This will take about one second, after which it will display PAGE ACCEPTED PAGE ACCEPTED for a couple seconds, and
then return back to the PAGER NO= PAGER NO= prompt.
2. Numeric and alpha-numeric pagers
If the pager is designated as a Numeric pager or an Alphanumeric pager in the OSMAC BaseOSMAC Base database, then
the LCD display will show NUMERIC PAGER NUMERIC PAGER or ALPHA PAGER ALPHA PAGER for one second, and then the LCD display will
show ENTER MESSAGEENTER MESSAGE. The user enters the message using the keypad into line 2 of the display. If the
message is longer than the length of the display, the display will automatically scroll down to the next line
as the message is entered. Pressing the DEL key deletes the previous character entered. Once the data is
entered, press the F1 key to send the page. The display will show PAGE ACCEPTEDPAGE ACCEPTED for a couple seconds and
then the display will return back to the PAGER NO= PAGER NO= prompt.
Note that:
• Only messages with numbers may be sent when using the built-in keypad.
• Alphanumeric messages may be sent to alphanumeric pagers when using an external keyboard or the
computer interface.
• The POCSAG characters "[", "]", "-", "space" and "U" may be sent to numeric pagers when using the
external keyboard, mobile radio or the computer interface.
3. Two-tone pagers
Two tone pagers accept a sequence of two tones. The CAPCODE is a number between 0 and 999. A large
number of standard tone plans are supported by the OSMAC BaseOSMAC Base. . Pagers with non-standard tone frequencies
may be programmed via the database upload command. After the paging tones are sent, an alert sound or a
voice message from the telephone interface or console may optionally be sent to the pager. Alternatively,
the phone patch may be initiated.
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.
