When the programmed time expires, the radio generates a warning tone and stops transmitting. The range for the TOT Dispatch Time is from 5 seconds to 600 seconds in step of 5 seconds.. 2) TOT Re-key a) TOT re-key specifies the time when transmission is prohibited after the time-out timer is activated. b) During the time of transmitting prohibition, if you press the PTT button, warning tone sounds and transmitting is prohibited. 3) TOT Pre-alert a) Before the time-out timer stops transmitting, the radio sounds pre-alert tone. b) After the alarm tone, if the transmitting time is longer than the preset time limit, the time-out timer will be activated. 4) TOT Reset a) TOT Reset is the delay time between releasing the PTT button and resetting the time-out timer. b) If the time of releasing the PTT button is shorter than the TOT Reset, the countdown of transmitting prohibition will continue. Battery Save The dealer can program the battery save type. If the battery save function has been set, 10 seconds after no signals being received or no operations being conducted, the radio enters the battery save mode. It will exit the battery save mode automatically after receiving signals or being conducted. Battery Save Types: Short, Middle, Long and OFF. Battery save function can increase battery active time. Low Battery Warning Low Battery warning tone sounds and RED LED flashes when the battery power goes below the preset value and you need to recharge the battery. If the battery voltage is too low, transmission is prohibited.
CTCSS/DCS The dealer can set CTCSS/DCS on the radio channels to ignore calls on the same channel from irrelevant radios. If a channel has been set with CTCSS/DCS, the squelch will be activated only when it receives the proper CTCSS/DCS signals. And only the radios set with the same CTCSS/DCS signaling as those on yours can hear your call. Note: Using a CTCSS/DCS channel doesn’t mean your calls are private. If the CTCSS/DCS tones of other radios are identical with those on yours, they can hear your calls. ■ User Template A user template includes PTT code-transmitting, encoding, decoding, Busy Channel Lockout, Call 1/2/3/4, RX squelch mode, TX conditions and decoding conditions, etc. Maximum 16 user templates are available on this radio. RX Squelch Mode The dealer can set conditions under which the speaker will be activated from the following 4 options: 1) CTCSS/DCS and Audio Squelch: The speaker will be activated only when both CTCSS/DCS and the selective signaling matched. 2) Audio Squelch: The speaker will be activated when the selective signaling matched. 3) CTCSS/DCS Squelch: The speaker will be activated when CTCSS/DCS matched. 4) Carrier Squelch: The speaker will be activated when carrier wave presents Scan When in scanning, the radio checks signals on each channel; it stops scanning and pauses on the channel on which signals are detected until the signals disappear. If a delay time has been set between the interval of signal disappearing and scanning restarting, the radio will stay on that channel if it receives any signals during the delay time. The operating channel of the radio will revert to the following channels automatically when you press PTT button during scanning. The dealer can select one among the following six options.: 1) Start channel When pressing PTT button, the radio will transmit from the channel described in the Start. 2) Selected channel When pressing PTT button, the radio will transmit from the channel selected. 3) Last called When pressing PTT button, the radio will transmit from the last channel that received a call. 4) Last used When pressing PTT button during the scanning, the radio will transmit from the last channel you used to talk. C ) Priority Scan
During scanning, if the priority channel has been set on the radio, when the priority channel receives signals the radio will automatically switch to the priority channel even the normal channel is receiving signals at that time. And the radio will stay on the priority channel till the signals disappear. The dealer can set the delay time between signal disappearing and continuing scanning. Temporarily Delete Noise Channel When scanning pauses on a channel, press and hold the button Programmed as “Temporarily Delete Noise Channel” to delete this channel temporarily from the scanning list. Note: The priority channel cannot be deleted. DTMF The dealer can set DTMF signaling in the Personality Template. The Call Alert / Selective Call, Message , ANI feature and so on can be set by your dealer. 5-Tone Signaling The dealer can activate or inactivate this function by programming. 5-Tone has 9 encoding formats: CCIR1, CCIR2, ZVEI1, ZVEI2, SVEI3, EEA, EIA, USER DEFINED 1, and USER DEFINED 2. The last tow formats are user defined. 1) 5-Tone Decode The decoding template is 5-tone decoding. If the decoding template matches the encoding template, decoding succeeds. When receiving proper 5-tone signaling, squelch will be activated according to the “RX Squelch Mode” defined by the user. You can receive the call and LED flashes orange. After the radio decoding succeeds, the radio will work according to the decoding call response set by the dealer. 2) 5-Tone Encode Encoding template consists of at least one and at most three encoding sequences and each decoding sequence can be set with 5-Tone, and DTMF. If it is set with 5-Tone, you need to program its content. If the PTT ID on the channel you select has been set with 5-Tone, 5-Tone signaling will be transmitted when making a call. Or transmit 5-Tone signal by pressing the Call 1/2/3/4 button,, which can be set by the dealer. 2-Tone Signaling This function can be enabled or disabled by dealers through programming software. 2Tone has 4 systems; the single tone continuous time, such as first tone or second tone, could be set by the dealer. 1) 2Tone decode If the received 2 tone is same as the template chosen then it can decode successfully. After the radio received the correct 2 tone signaling, according to the Receive squelch mode set by the user, the squelch will be ON. Then, the radio can receive the call and the orange LED light flashes. After decoding successfully, the radio can work according to the decode call response set by the
dealer. 2) 2Tone encode The encoding template is set in the 2 tone call list. The details must be set if encoding is ON. The radio transmits the 2 tone signaling when the programmed call button is pressed. (The side button could be programmed as Call1/2/3/4). This function is programmed by the dealer. MDC Signaling This function can be enabled or disabled by the dealers through programming software. MDC has 4 systems, in which different main ID, group ID, etc., could be set by the dealer. 1) MDC decode The option MDC system can be set through the RX signaling system in the personal template. If the received MDC code is same as the one set in the system, it can decode successfully. After the radio received the correct MDC signaling, according to the Receive squelch mode set by the user, the squelch will be ON. Then, the radio can receive the call and the orange LED light flashes. 2) MDC encode If the PTT ID of the chosen channel is set as MDC, the MDC code will be transmitted when calling. ■ Troubleshooting No. Problems Solutions 1 The radio cannot be switched on or no display after switched on. z Battery pack may not be installed properly.
