When paging signal is received, a beep sound and the display will inform you that someone has you paged.! The paging station can be identified by means of its individual code.
☆ Code Squelch operation is available when an optional DTMF unit DTF145 is installed. The Transceiver
will hear certain stations using the identical code only. ’
☆ Tone Squelch operation is available when an optional tone squelch unit CTS145 is installed. The Transceiver

☆ DTF145 and CTS145 can be used together allowing you the simultaneous operation of Code Squelch and Tone Squelch.
☆ An optional High Power Rechargeable Battery Pack or an external Power Supply
of 13.8V enable powerful transmission (over 5W).
☆ A wide range of acceptable external Power Supply
voltages (5.5 to 16V DC) allows you to power it from an automobile battery ([specified for 12V only).
☆ High Sensitivity.
☆ Up to 20 memory channels are available, 10 in each M and M memory group.
☆ Independent tone frequencies and offset frequencies can be programmed for each of 20 memories.
☆ Internal Dual-Watch allows the Transceiver
☆ the selected dial-frequency and the stored frequency in memory address
☆ the selected dial-frequency and any other memory frequency
☆ the selected dial-frequency and each memory frequency under scanning in sequence, (up to 20 channels)
☆ the selected dial-frequency and call frequency
☆ Either Pause or Busy scan functions can be selected. Scanning of the dial-frequency provides a 1 MHz scan, all band scan and programmed scan. Scanning of a memory frequency provides M memory group scan. M memory group scan, all memory scan and MS.M scan.
☆ A single puchbutton press opens the squelch so you can easily check the volume setting.
☆ A Battery-Save function allows you to reduce the current drain during Receiver
☆ An Auto-Power Off function reduces the current drain if you forget to turn the Transceiver
