4.1.7 Voice Prompts
This mode selects whether beeps or voice prompts are used to confirm radio and phone operations
with the OSMAC Base. The language of the voice prompts is determined by which firmware file has
been loaded. If you are interested in a language other than English, contact your distributor for
availability.
4.1.8 Warmup Signal
If this mode is enabled, then a special "warmup" signal is transmitted for a brief period of time at the
beginning of each page. This is required for more reliable operation by some pagers.
4.1.9 Rings to Answer
The phone will be answered after the number of rings specified. Enter 0 to answer the phone
immediately after detection of a phone ring.
4.1.10 Number Done Delay
When entering a phone number to be dialed in the autopatch mode, this programmable parameter
determines how long the unit will wait after each digit is pressed until assuming that all digits have
been entered. After this delay, the phone number will automatically be dialed. Users not wishing to
wait for this timeout may alternatively press the # key to terminate the phone number and tell he unit to
dial the phone number immediately.
4.1.11 Transceiver Setup
The OSMAC Base either contains a two-way transceiver or works with an external transceiver. In
either case, the factory has programmed the correct Transmitter Type, Carrier Detect inversion,
Transmit Data inversion, and the TX Bandwidth. The user should not change these settings or
improper operation will result.
4.1.12 TX/RX Switch Time
This parameter is used by the autopatch to determine the sampling time to listen for the mobile radio
user when transmitting the phone user's voice. If it is set too small, the mobile radio user will not be
able to interrupt the transmitter when in the autopatch mode. If it is set too large, then the transmitter's
dropout time will be excessive.
4.1.13 Transmit and Receive Frequencies
Enter the desired transmit or receive operating frequency using the number keys. The decimal point
will automatically be entered. Use the DEL key to delete any correct entries. Press the F1 or "-"key
to accept the new frequency.
4.1.14 Transmit and Receive Signaling
Carrier Squelch operation may be desirable if there are no other users on the channel and there is no
interference. In this mode, the two-way-radio users will be able to hear the paging signals transmitted
by the OSMAC Base. To enable this mode, press 1 to select (CARRIER ONLY). Press the "-"keyto
exit the menu.
If there are other users sharing the channel, there is excessive interference, or the two-way-radio
users do not want to hear the paging signals, then CTCSS operation should be used. In this mode, a
low frequency tone is transmitted along with the desired audio. The receiver will only be enabled if this
tone is present at the correct frequency.
To enable this mode, press 2 to select CTCSS, then use the arrow keys to select the desired tone
frequency. Press the "-"orF1 key to accept the frequency and exit the entry mode.
