Page 12: Epcs (Enhanced Paging & Code Squelch)
Using the Squelch Feature EPCS (Enhanced Paging & Code Squelch) The FT-25R/E includes an Enhanced CTCSS tone encoder/decoder and a dedicated microprocessor providing paging and selective calling features. The squelch permits directing calls to specific stations (Paging), and receiving only the calls directed to stations programmed with a similar code (Code Squelch). -
Page 13: Activating The Enhanced Paging & Code Squelch System
3. To disable the EPCS function, just repeat the above procedure, Press the [▲] or [▼] key to select “OFF” in step 1 above. During EPCS operation, the FT-25R/E may be set up to sound a ringing “bell” alert when an EPCS call is coming in, as described previously.See page 11 for details. -
Page 14: Paging Answer Back
Using the Squelch Feature Paging Answer Back When the PTT switch is pressed in response to answer a paging call, the FT-25R/E transmits the same CTCSS tone pair. This tone pair will open the Code Squelch of the calling station. If preferred, the FT-25R/E may be setup to respond to the pager calls automatically (“transpond”). -
Page 15: Memory Bank Operation
Memory Bank Operation The large number of memories available in the FT-25R/E could be difficult to manage without some means of organizing them. Fortunately, the FT-25R/E includes a provision to divide the memories into as many as ten Memory Groups. The memories can be categorized in a manner convenient for the operator. -
Page 16: Removing A Memory Channel From A Memory Bank
• If assigned memory channels still remain in the Memory Bank, the display will return to a Memory Bank channel. • If there is no assigned memory channel in the Memory Bank, the display will return to the Memory channel. FT-25R/FT-25E Advance Manual... -

Page 23: Automatic Lamp Illumination On Scan Stop
Scanning Automatic Lamp Illumination on Scan Stop The FT-25R/E will automatically illuminate the LCD/Keypad Lamp whenever the scanner stops on a signal; this allows you to see the frequency of the incoming signal better at night. Note that this will, of course, increase the battery consumption, so be sure to switch it off during the day (the default setting is “ON”). -
Page 24: Emergency Channel Operation
Emergency Channel Operation The FT-25R/E includes an “Emergency” feature which may be useful if you have someone monitoring on the same frequency as your transceiver’s VHF “Home” channel. See FT- 25R/E Operating Manual for details on setting the Home channel. -

6.25; 10; 12.5; 15; 20; 25; 50; or 100 kHz per step, as well as an automatic (“AUTO”) step selection based on the current operating frequency. The FT-25R/E is set up at the factory in the “AUTO” configuration, which probably is satisfactory for most operation. However, another step setting may be important to your operating requirements. -
Page 31: Tx Battery Saver
5. Press the PTT switch to save the setting and exit to normal operation. TX Battery Saver The FT-25R/E also includes a useful Transmit Battery Saver, which will automatically lower the power output level when the last signal received was very strong. For example, when operating in the immediate vicinity of a repeater station, there is generally no reason to use the High Power output in order to achieve full-quieting access to the repeater. -

Inversion Scramble enabled, will not be able to clearly hear the conversation. To use this feature, the other (FT-25R/E) station must also complete the following procedure to set Inversion Scramble. -
Page 35: Cloning
Cloning The FT-25R/E includes a convenient “Clone” feature, which allows the memory and configuration data from one transceiver to be transferred to another FT-25R/E. This can be particularly useful when configuring a number of transceivers for a public service operation. Here is the procedure for cloning data from one transceiver to another: 1. -
Page 36: Set (Menu) Mode
Set (Menu) Mode Many FT-25R/E functions have already been described in previous chapters, The Set Mode Menu is used to configure the transceiver parameters, some of which have not been detailed previously.
