![18 FTM-3100R Operating ManualAdvanced OperationRepeater OperationThe FTM-3100R includes the ARS (Automatic Repeater Shift) function, which permits communication through repeaters automatically, by simply setting the receiver to the re-peater frequency.1. Tune to the repeater frequency.2. Press the PTT to transmit. During transmission, radio waves having an 100.0 Hz* tone signal are emitted on the frequency offset from the receive frequency by 0.6 MHz*. *: Depends on the transceiver version.Note: From the Setup Menu, you can change the repeater setting.RPT ARS 29 à Deactivates the ARS function.RPT FREQ 30 à Allows changing the repeater shift frequency offset.RPT SFT 31 à Allows setting the repeater shift direction.Checking the Repeater Uplink (Input) FrequencyIt is often helpful to be able to check the uplink (input) frequency of a repeater, to see if the calling station is within direct (“Simplex”) range.To do this, just press the [REV(DW)] key. You’ll notice that the display has shifted to the repeat-er uplink frequency. Press the [REV(DW)] key again to cause operation to revert to normal monitoring of the repeater downlink (output) frequency. While listening on the repeater input frequency using the [REV(DW)] key, the repeat-er offset icon will blink.BlinksApplication for FCC / IC FCC ID: K6620523X51 / IC: 511B-20523X51](https://usermanual.wiki/Yaesu-Musen/20523X51/User-Guide-2926934-Page-3.png)

These include:r 199 “basic” memory channels, numbered “1” through “199”.r A “Home” channel, providing storage and quick recall of one prime frequency.r 10 sets of band-edge memories, also known as “Programmable Memory Scan” chan-nels, labeled “L0/U0” through “L9/U9”.Each memory may be appended with an alphanumeric label of up to 8 characters, for quick channel recognition.Memory Storage1. In the VFO mode, select the desired frequency, repeater shift, CTCSS/DCS tone, and TX power level.2. Press and hold the [V/M(MW)] key for one second. A memory number will appear in the bottom right corner of the display.Note: If the channel number is blinking, there currently is no data stored on that channel; if the channel number is not blinking, that channel is currently “occupied” by other frequency data.VOLDIALDW MWSETUPREV V/MMHzSQL TXPO3.

![26 FTM-3100R Operating ManualReset Procedure/CloneReset ProcedureIn some instances of erratic or unpredictable operation, the cause may be corruption of data in the microprocessor (due to static electricity, etc.). If this happens, resetting the microprocessor may restore normal operation. Note that all memories will be erased if you do a complete microprocessor reset, as described below.Microprocessor ResettingTo clear all memories and other settings to factory defaults:1. Turn the radio OFF.2. Press and hold the [TXPO], [MHz(SETUP)], and [V/M(MW)] keys while turning the radio on. The “ALL RESET PUSH V/M KEY” notation will scroll on the display.3. Press the [D/M(MW)] key momentarily to reset all settings to their factory defaults (press any other key to cancel the Reset procedure).Set Mode ResettingTo reset the Set (Menu) mode settings to their factory defaults, while leaving other set-tings unchanged:1. Turn the radio OFF.2. Press and hold the [TXPO] and [MHz(SETUP)] keys while turning the radio on. The “SET MODE RESET PUSH V/M KEY” notation will scroll on the display.3. Press the [D/M(MW)] key momentarily to reset the Set (Menu) mode settings to their factory defaults (press any other key to cancel the Reset procedure).CloneThe FTM-3100R includes a convenient “Clone” feature, which allows the memory and configuration data from one transceiver to be transferred to another FTM-3100R.This can be particularly useful when configuring a number of transceivers for a public service operation.Note: For details, refer to the Advanced Manual (download from the Yaesu website).Application for FCC / IC FCC ID: K6620523X51 / IC: 511B-20523X51](https://usermanual.wiki/Yaesu-Musen/20523X51/User-Guide-2926934-Page-11.png)

If you want to turn the beeper off (or back on again).Note: If you want to turn the beeper off (or back on again), see Setup Menu Item “3 BEP KEY” on page 29.Display BrightnessYou can adjust the display brightness.Note: See Setup Menu Item “16 LCD DMMR” on page 30.Time-Out-Timer (TOT)The “Time-Out Timer” (TOT) feature is designed to force the transceiver into the “receive” mode after a preset time period of continuous transmission (the default is 3 minutes).Note: See Setup Menu Item “39 TOT” on page 31.Automatic Power Off (APO)The “Automatic Power-Off” (APO) feature will turn the radio completely off after a user defined period of PTT or key/button inactivity.Note: See Setup Menu Item “1 APO” on page 29.Busy Channel Lock-Out (BCLO)The BCLO feature prevents the transmitter from being activated whenever a signal strong enough to break through the “noise” squelch is present on the frequency.Note: See Setup Menu Item “2 BCLO” on page 29.TX Deviation LevelYou can reduce the receiver bandwidth and transmit deviation when operating on closely spaced frequencies (channel spacing of 12.5 or 15 kHz). The reduced transmitter devia-tion will minimize adjacent channel interference to other users.Note: See Setup Menu Item “45 W/N DEV” on page 31.MIC Gain SettingAt the factory, the microphone gain has been programmed so that it should be satisfac-tory for the supplied MH-48A6JA Microphone. If you use an after-market microphone or connect a TNC, you may wish to set a different Mic Gain level.Note: See Setup Menu Item “18 MIC GAIN” on page 30.Application for FCC / IC FCC ID: K6620523X51 / IC: 511B-20523X51](https://usermanual.wiki/Yaesu-Musen/20523X51/User-Guide-2926934-Page-12.png)
