Plug the adapter into an AC wall outlet and the indicator turns green. Power adapterBattery Charger
PT6500 User’s Manual Page 4 of 30 Place the battery or transceiver into the charger slot, and make sure the transceiver has been turned off. Make sure the battery is well connected with charger, then the indicator turns red or flashes, then the charger gets in the state of charging automatically. When battery is fully charged the indicator turns green. The performance will be at the best condition if you remove the battery when the green indicator is on. Then remove the power adaptor from the wall outlet. The charger will enter the protection mode when the yellow indicator flashes, which means the temperature or the circuit is abnormal. Do not charge the battery at this moment, just remove the battery and turn off the power of the charger. Notes: * The battery is not fully charged in the factory. Before the initial use, please charge the new battery. * The KB-36A Ni-MH battery/KB-36C Li-ion battery of this company is adaptable with this machine. * When you charge the battery the first time or after long time storage (2 months), several times of charging is needed. Make sure the battery is charged at least once every three months. * Do not charge the battery again if it is charged fully or not in the low-pressure warning mode, otherwise, its life will be shortened or it will be damaged. Remove the battery from the charger after charging. * When you use the KB-36A battery, and the transceiver is in the low-pressure warning
PT6500 User’s Manual Page 5 of 30 mode, recharge the battery before use. Do not power on by force, otherwise, its life will be shortened or it will be damaged. * There is a protection circuit in KB-36C battery, so the power will be cut off at too low battery. ◆Installing/Removing the battery pack To install the battery pack: Match the 3 bulges of the battery pack with the corresponding holes at the rear Button of the transceiver.

This function can only be set by the dealer, and you have to be equipped with the specified earphones. Before using VOX, you must set VOX gain level. Such setting enables the radio to identify the voice volume. If the microphone is too sensitive, the background noise will trigger the radio to transmit. If the microphone is not sensitive enough, it cannot receive your voice when you speak. Make sure to adjust CHANNEL 1 401.66500 CH 1 CHANNEL 1 CHANNEL 1
PT6500 User’s Manual Page 24 of 30 VOX gain level to proper sensitivity. ■ Auxiliary Functions) ◆ Time-out Timer (TOT) TOT timer: Time-out timer can prevent any caller from occupying one certain channel for an extended period of the time. The radio is set with a continuously transmitting limit. If the radio is continuously transmitting longer than the time preset by the dealer, the radio will stop transmitting and warning TOT forbidden period: A period in which the radio is forbidden to transmit after its overtime activity. During the period, if the PTT key is pressed, there will be a warning tone, and transmitting is forbidden. TOT pre-warning: The pre-warning will sound before the TOT action. After the sound of the warning, the timer will take action when the transmitting time has gone beyond the limit. TOT reset: The time delay from releasing the PTT key to the resetting of the timer is limited. The countdown will go on if the time after releasing the PTT key is shorter than the reset time. ◆ Battery Saving The dealer can set the type of this function by programming. If the battery saving function is on, 10 seconds after the radio hasn't receive any signals or no operation is being conducted, the radio enters battery saving mode. When a signal is received or any operation occurs, it exits battery saving mode automatically. The types include: 1：1, 1：2, 1：4 and off. The automatic battery saving function decreases the power consumption. ◆ Voice Annunciation of Channel Number The dealer can turn on or turn off this function by programming. While switching to another channel, you can hear the voice annunciation of the current channel number. ◆CTCSS/ DCS The dealer can set CTCSS/DCS tones on radio channels, which enable you to ignore (not hear) calls
PT6500 User’s Manual Page 25 of 30 from other irrelevant parties who are using the same channel. When you receive a signal that has a tone different from the one set on your radio, you will not hear the signal. Likewise, signals that you transmit will only be received by parties whose CTCSS/DCS tones are the same as yours. Note: Using a CTCSS/DCS channel doesn't mean your calls are private. If other parties' CTCSS/DCS tones are identical with yours, they can hear your calls. ■User’s resolution ◆Busy Channel Lockout (BCL) Busy Channel Lockout can prevent you from interfering other radios that using the same channel. Press the PTT button when the channel is busy, the radio with BCL function active will make warning sound and prohibit transmitting. To stop the warning sound, please release the PTT button and the radio returns to receiving mode. The dealer may provide the following two lock mode: Carrier wave: it will be locked if there is any Carrier wave; Carrier wave+ CTCSS/DCS：transmitting is permitted if there are matched CTCSS/DCS in the channel. ◆Receiving squelch mode The dealer may set the condition under which to turn on the speakers: 1. CTCSS/DCS and audio squelch: only when the CTCSS/DCS and optional signaling are patchable. 2. Audio squelch: once the optional signaling is matchable. 3. CTCSS/DCS squelch: when the CTCSS/DCS is matchable. 4. Carrier wave squelch: once there is any Carrier wave. 5. CTCSS/DCS and audio squelch: when the CTCSS/DCS is matchable, or when optional signaling are matchable. ◆DTMF signaling The dealer can set this function by programming. There are 4 systems of which the parameters can be set, e.g.: group call ID No., * and # sound, etc. After set a DTMF code in the “code sequence” , select DTMF system in the “DTMF code”, then select the correspondent DTMF code cable in the “user’s resolution” and transfer it with PTT. Set a DTMF code in the “deenencoding sequence”, add the sequence into the decoding cable in “DTMF decoding”, then select the correspondent decoding cable. The dealer may also set the “decoding replay”.
PT6500 User’s Manual Page 26 of 30 ◆2TONE signaling The dealer can set this function by programming. There are 4 systems of which the parameters can be set, e.g.: the duration of the first and the second tone, the duration of the long tone and audio spacing, etc. Select the audio frequency（3106.0～288.0hz step size 0.1hz）in “encoding sequence”, and whether the tones sent are long or two tones, select 2TONE system in “2TONE List”, then select the correspondent 2TONE code cable in the “user’s resolution” and transfer it with PTT. Select the audio frequency（3106.0～288.0hz step size 0.1hz）in “decoding sequence”, and whether the tones received are long or two tones, then select the correspondent decoding cable in the “user’s resolution”. The dealer may also set the “decoding replay”. ◆ Transmit start/over signaling (PTT ID) The identify signal of transmit start/over are used to maintain or disconnect some repeaters or phone system. “Transmit start” is used to connect routine repeaters and auxiliary facilities. If the ID transmitted is matchable with that of the repeaters, the repeaters and auxiliary facilities are available. “Transmit over” is used to disconnect routine repeaters and auxiliary facilities. If the ID transmitted is matchable with that of the repeaters, the repeaters and auxiliary facilities are disconnected. ■ Problems and troubleshooting No. Problems Solution 1 No display after switched on.
