IMPORTANT NOTE: Some keyboards are extremely sensitive to the high RF fields present when an
antenna is connected directly to the rear of the OSMAC Base . The keyboard may stop functioning
properly after the OSMAC Base transmitter is turned on. If this situation occurs, it is recommended that
the antenna be mounted at least several feet from the OSMAC Base or that a different brand of keyboard
be used.
2.4 Display
There is a two-line, twenty-character LCD display on the OSMAC 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 Base is ready to send a page when the LCD display shows:
This means the OSMAC 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 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 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 for a
couple seconds, and then return back to the 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 Base
database, then the LCD display will show NUMERIC PAGER or ALPHA PAGER for one second, and
then the LCD display will show ENTER 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 ACCEPTED for a couple seconds and then the display will return back to the
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 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.
