Hold the PTT lever on the microphone while pressing the required DTMF tones. The tones will be transmitted as the keys are being pressed. 13 © Midland Radio Corporation Base Tech II Base/Repeater Station Operator’s Manual Attach Decode No. "ON" format Attach Decode No. "ON" automatically encodes the user’s DTMF decode number after the encode number. This can be used for any purpose. Enter the required DTMF tones (up to sixteen tones, except "B" tone) and then transmit the total tone sequence (including the users decode number) by pressing the [#] key. All tones will be transmitted in one continuous sequence after pressing the [#] key. Pressing the [ ] key will delete the last number entered. Always confirm that the LCD is clear before proceeding, as it may take up to 5 seconds for the tones to be sent. For example, assume that your decode number is 12345, and that you wish to encode number 12346. You will input 12346, and then press the [#] key. The Base Tech II Base Repeater will encode "12346B12345". The called radio will display “12345” in their LCD indicating the calling party's number is "12345". NOTE: The "B" tone is used as the delimiter in this encoding format and therefore CANNOT be used as a DTMF tone. Pressing the [SHIFT] key and then the [#] will encode ONLY the encode number (and not the decode number). Redialing with DTMF If, during the programming of the Base Tech II Base Repeater, the field has been set to "OFF", the redialing function operates as follows: Press [SHIFT], then press [#] and the Base Tech II Base Repeater will redial the last encoded DTMF number. If, during the programming of the Base Tech II Base Repeater, the field has been set to "ON", the redialing function operates as follows: Press [#] and the Base Tech II Base Repeater will redial the last encoded DTMF number with the Base Tech II Base Repeater's programmed decode number. Press [SHIFT], then press [#] and the Base Tech II Base Repeater will redial the last encoded DTMF number without the Base Tech II Base Repeater's programmed decode number. Restoring the last DTMF number to the LCD Display It is possible to restore the last encoded DTMF number to the LCD display, provided the field has been set to "ON" during the programming of the Base Tech II Base Repeater. First, confirm that the LCD is NOT displaying any DTMF numbers. Then press [V] and the last encoded DTMF number will be displayed in the LCD display. It is possible to edit this number at this time by pressing the [V] key (which will erase the last number) or by pressing the required keys to add additional numbers. Encoding DTMF numbers with the 5-Tone system enabled It is possible to enter DTMF numbers even with the 5-Tone system enabled. This function must be enabled during the programming of the Base Tech II Base Repeater by setting the field in the <5Tone Encode Menu> to "ENABLE". To enter a DTMF number (with 5-Tone signaling enabled), the user must press the PTT lever while entering the first DTMF number.
