3915 OPERATOR CONVENIENCESThe transceiver generates the following warningbeeps even if the beep function is turned OFF.• DC voltage error {page 2}.• PLL circuit malfunctions.Note: A beep output level is linked the VOL control position.BEAT SHIFTSince the transceiver uses a microprocessor tocontrol various functions of the transceiver, the CPUclock oscillator’s harmonics or image may appear onsome spots of the receiving frequencies. In this case,turn the Beat Shift function ON.1 Press [MNU].2 Turn the Tuning control or press [ ]/ [ ] to selectMenu No. 25 (BEAT SHIFT).3 Press [sssss] or [MNU].4 Turn the Tuning control or press [ ]/ [ ] to select“ON”.5 Press [sssss] or [MNU] to store the setting.DISPLAY CONTRASTYou can adjust the LCD contrast level from 1(weakest) to 16 (strongest) by accessing Menu No.16 (CONTRAST). A default level is 8.1 Press [MNU].2 Turn the Tuning control or press [ ]/ [ ] to selectMenu No. 16 (CONTRAST).3 Press [sssss] or [MNU].4 Turn the Tuning control or press [ ]/ [ ] to adjustthe LCD contrast.• The relative contrast level appears in a bar-graph.5 Press [sssss] or [MNU] to store the setting.FREQUENCY STEP SIZEChoosing the correct frequency step size is essentialin order to select your exact receive frequency usingthe Tuning control or pressing [ ]/ [ ]. You canselect your desired frequency step size from:5 kHz, 6.25 kHz, 8.33 kHz (118 MHz band only),9 kHz (AM broadcasting band only) , 10 kHz,12.5 kHz, 15 kHz, 20 kHz, 25 KHz, 30 kHz, 50 kHz,100 kHz.The default step size for the amateur radio bands areas follows.dnaB oidarruetamAdnab A6F-HT E7F-HTdnab-AzHM441 zHk5 zHk5.21zHM022 zHk02 —zHM044/034 zHk52 zHk52dnab-BzHM441 zHk5 zHk5.21zHM022 zHk02 zHk5.21zHM044/034 zHk52 zHk52zHG2.1 zHk52 zHk52For B-band, refer to the page 35 for the defaultfrequency step size for other frequency bands. Thetransceiver stores the frequency step size parameterfor each band independently. You can also furtherfine tune the frequency in LSB, USB, AM, CW modeson the B-band. Refer to FINE tuning function{page 36}.Note: If you change the frequency step size that does not match thecurrent operating frequency, the transceiver automatically adjust thefrequency that matches new frequency step size.LAMPYou can illuminate the transceiver display by pressing[LAMP]. Approximately 5 seconds after releasing[LAMP], the light goes OFF if no other key ispressed. Pressing any key other than [LAMP] whilethe display is lit, restarts the 5-second timer; pressing[LAMP] turns OFF the light immediately.To keep the light ON continuously, press [F], [LAMP].The light remains ON until you press [F], [LAMP].LOCK FUNCTIONLock function disables the most of keys to preventyou from accidentally activating a function orchanging the current settings.Press [F] (1 s) to toggle Lock function ON or OFF.• “ ” appears when this function is ON.However, the following keys are not locked:[LAMP], [MONI], [SQL], [PTT], [F] (1 s), [ ], and[F] then [LAMP].Note: The Tuning control is also locked. To unlock the Tuningcontrol while the Lock function is ON, turn the Tune Enable functionON.n Tune EnableEven if the Lock function is ON, you sometimes wantto turn the Tuning control to change the frequency.In this case, turn this function ON.1 Press [MNU].2 Turn the Tuning control or press [ ]/ [ ] to selectMenu No. 7 (TUNE ENABLE).3 Press [sssss] or [MNU].4 Turn the Tuning control or press [ ]/ [ ] to select“ON”.5 Press [sssss] or [MNU] to store the setting.
