Resumen del manual
TH-55AT/55E: Additionally ON when the Battery Saver and Automatic Power Off function have been cancelled. ® 5 kHz tuning step indicator This indicator lights during VFO operation when tuning in 5 kHz steps. 500 Hz dot (TH-25E/TH-45E only) This indicator show 500 Hz. @ T indicator This indicator is ON when the Tone function is active. @ CTCSS indicator This indicator is ON when the CTCSS function is active. * T. ALT indicator ^ This indicator is ON when the Tone alert system is active. The indicator will flash when a signal is received. @> Memory channel indicator This indicator is used to show the selected memory channel number. © Memory indicator This indicator lights during Memory Recall mode, and flashes during Memory entry. 9 TH-45A MONITOR switch When operating in the CTCSS (Tone Squelch) mode you can use this key to determine if the frequency is in use before transmitting. Pressing this key will disable the CTCSS function as long as the key is held depressed. Lamp switch This switch is used to control the night lamp on the LCD display. The lamp will turn itself OFF automatically 5 seconds after the last key operation. PTT (Push To Talk) switch Press this switch whenever you wish to transmit. TH-45AT @ Release button Press this button up to release the battery pack. @) F. Lock key This key will deactivate all functions except the Lamp, MONI, PTT functions. (0) Speaker (fi) Microphone # Battery case © SP jack This jack is used to connect an external speaker or earphone. The recommended impedance is 8 I). © MIC jack This jack is used for connection of an external microphone. The use of an electret type microphone is recommended. Input impedance is 2 kfl and the DC voltage on this terminal is Approx. 4 V (MAX 3.5 mA). Note:-- The use of a dynamic microphone is not recommended. 10 (§) DTMF PAD (with the TH-25AT/45AT/55AT) This key pad is used in conjunction with a repeater to provide AUTOPATCH capabilities. @ M (Memory) key This key is used to enter a frequency, offset, etc. into the desired Memory channel.. When this key is pressed during Memory channel operation the contents of the Memory channel are duplicated in the VFO, and the transceiver returnes to VFO operation. The contents of the memory are not lost during this procedure. (§) CTCSS key This key is used to select the CTCSS (Tone squelch) function. © SHIFT key This key is used to select the desired transmitter offset for repeater operation. When the offset function is ON, ■+■ or [=] will be displayed in the display. <§> REV key Pressing the REV key allows you to reverse the transmit/receive frequencies during repeater operations. This will allow you to check the input of the repeater or to operate on a reverse repeater pair. (0) HI-LO switch This switch is used to select the transmit output power. TH-25A/45A SERIES TH-55AT SERIES @ RIT control (TH-55AT/55E only) When the transmit frequency of the distant station drifts a little bit during the QSO, but you do not wish to alter your transmit frequency to compensate, you may wish to make use of the RIT control function. This control allows shifting the receive frequency apploximate-ly ±5 kHz without shifting the transmit frequency. m HI LO 11 3-2 RECEIVER OPERATION Connect the battery pack, and the supplied antenna. Set the controls as follows: 1. Rotate the POWER (VOL) control clockwise to turn the transceiver ON. A frequency will appear in the display. 2. As the VOL control is rotated clockwise either background noise or a QSO will be heard coming from the speaker, provided the CTCSS and Squelch are not ON. 3. To eliminate the no signal noise turn the SQL control clockwise to the point the background noise just disappears. This point is known as the Squelch Threshold point. 4. Select the desired operating frequency using the tuning control. Frequency Selection Press the \/FO key. An operating frequency will appear in the display. • VFO Mode 1. Press the VFO key. 2. Turn the tuning control to increase/decrease the frequency. The step size is determined by the location of the VFO indicators (See Step Size Selection below). • MHz Mode 1. Press the MHz key. The MHz indicator will begin flashing. 2. The tuning control will now increase/decrease the operating frequency in 1 MHz increments. 3. The tuning step will revert to the VFO mode 5 seconds after you stop turning the tuning control. 12 Step Size Selection 1. Press the VFO key. 2. Press the M key. 3. Within 5 seconds of pressing the M key press the MHz key. The VFO indicator will toggle between 5 kHz and 10 kHz (See the chart below for your transceiver.) each time this sequence is performed. (kHz) TH-25A/25AT TH-25E/45E TH-45A/45AT TH-55AT/55E STEP SIZE 5/10 12.5/5 25/5 25/12.5 Note:- If you are already in the VFO mode you can skip step number 1. 3-3 TRANSMITTER OPERATION CAUTION:- Ensure that an antenna with a low standing wave ratio (SWR) is attached to the antenna co...
