manual abstract
(Because of DC voltage is present at the plug.) • When the plug is inserted in this jack, the built-in microphone is automatically disconnected. (D SP jack (Speaker jack) • Connect an external speaker or earphone. • Used with the MIC jack, for optional SMC-30 or HMC-1. • When the plug is inserted in this jack, the built-in speaker is automatically disconnected. 0 Antenna connector • Insert the supplied helical antenna and rotate to the right to secure. (D Tone switch • Activates the sub tone (TH-41 BT/31 BT/21 BT). • Tone unit is the optional TU-6 (TH-41 A/31 A/21 A). • Activates 1 750 Hz tone (TH-41 E/21 E). 0 +5 kHz switch • When the switch is ON the operating frequency is 5 kHz higher than indicated by the thumb wheel switches. 0 Frequency setting switches (Thumb wheel switches) A.....Used to set to 1 MHz. B.....Used to set to 100 kHz. C.....Used to set to 10 kHz. 0 ON AIR indicator • Lights for transmission. • When this indicator lights dimly, replace the batteries with new ones. 0 SQ control (Squelch control) • Used to eliminate noise at non-signal condition. For normal operation, turn the knob clockwise to the point at which noise just disappears. (S) PTT switch (Press-To-Talk switch) • Press this switch and speak into the micro phone for transmission. • The microphone is built in the same place as the speaker. (11) Hi/Low switch • Used to adjust the transmission output. • At Hi position, the output power is 1 W. At Low position, the output power is about 1 50 mW. 7 (H) TX offset switch TH-41 A/41 BT "S" Transmit and rec eive frequency are the same. (Also known as "Simplex".) "+" Transmit frequency is 5 MHz higher than the receive frequency. Transmit frequency is 5 MHz lower than the receive frequency. TH-41E Shifts the transmit frequency for repeater operation. "S" Simplex (receive and transmit frequencies are the same). "D - A" Sets the transmit frequency 7.6 MHz lower than the frequency set by the thumb wheel switches. "D - B" Switches the transmit frequency down 1.6 MHz from the receive frequency. TH-31 A/31 BT Shifts the transmit frequency for repeater operation. "S" Simplex (receive and transmit frequencies are the same). "REV” Sets the receive frequency 1.6 MHz lower than the frequency set by the thumb wheel switches. Switches the transmit frequency down 1.6 MHz from the receive frequency. TH-21 A/21 BT "+" Transmit frequency is 600 kHz higher than the receive frequency. Transmit frequency is 600 kHz lower than the receive frequency. "S" Transmit and receive frequency are the same. (Also known as "Simplex".) TH-21E Shifts the transmit frequency for repeater operation. "S" Simplex (receive and transmit frequencies are the same). "REV" Sets the receive frequency 600 kHz lower than the frequency set by the thumb wheel siwtches. Switches the transmit frequency down 600 kHz from the recieve frequency. 8 (H) Tone frequency setting switches (6P dip switches) (TH-41BT/ 31 BT/21 BT) Tone frequency setting...
