This function will not be disabled after programming. ) Advanced Operations The following functions are programmable by your dealer. CTCSS/CDCSS Set up talkgroups with unique CDCSS/CTCSS to prevent unwanted conversations on the same frequency. If CTCSS/CDCSS has been set on the current channel, CTCSS/CDCSS match is required for the radio to unmute to an incoming signal. If CTCSS/CCSS is not set, the radio can receive calls from all users operating on the same frequency. Your dealer may set CTCSS/CDCSS for some channels. This feature does not mean that your conversation will not be heard by others. Radios with the same CTCSS/CDCSS or with no CTCSS/CDCSS, can receive calls from you. Battery Save The Battery Save feature will be automatically activated once no activity is present on the channel and no operation is performed (no key press and no knob selection), for extended operation time. Once the radio detects no activity on the channel and no operation performed (no key press and no knob selection) during radio standby time, it will automatically enter sleep 15

mode ten seconds later. Pressing any key or receiving a signal will cause the radio to exit from Battery Save and restore it to normal operation. Power Adjust Users can switch the Tx power level between high and low power by pressing the programmed Power Adjust key. Time-out Timer (TOT) The TOT timer limits the amount of time the radio can continuously transmit on a channel. This can also protect your radio from damage due to excessive transmission. If the user holds down the PTT key longer than the preprogrammed time period, the radio will automatically stop transmitting and generate a warning tone. To stop the warning tone, release the PTT key. Your dealer may program the alert tone that sounds before the TOT timer nearly expires. Battery Strength Indicator TC-320 allows you to simply press the programmed Battery Strength Indicator key to illuminate the Status Indicator, which gives different indications representing battery strength levels. To exit the indications, release the key. The Status Indicator gives the following indications to represent corresponding battery strength levels: Battery Strength Status Indication 70%-100% Status Indicator solidly glows green. 50%-70% Status Indicator solidly glows orange. 30%-50% Status Indicator solidly glows red. 10%-30% No indication is given when the programmed key is pressed; Status Indicator flashes red while the radio is operating. Less than 10% No indication is given when the programmed key is pressed. While the radio is in standby mode, Status Indicator flashes red and a low-pitched tone sounds at intervals of ten seconds. If PTT key is 16

pressed at the moment, the radio will give an alert indicating that transmission is prohibited. Monitor z Squelch Off Purpose: In this mode, the speaker is unmuted in any condition so as to receive any sound on the current channel. When audio signal is received on the channel, audio will be heard. Otherwise, background noise will be heard. Operation: Press the Monitor key to enter this mode, and press it again to exit. z Squelch Off Momentary Purpose: Refer to Squelch Off. When audio signal is received on the channel, audio will be heard. Otherwise, background noise will be heard. Operation: Hold down the programmed key continuously to enter this mode, and release the key to exit. z Monitor Purpose: In this mode, the receiving party can receive incoming calls from the transmitting party regardless of CTCSS/CDCSS condition. If the carrier condition is not satisfied, the receiving party will fail to receive any incoming calls. Operation: Press the Monitor key to enter this mode, and press it again to exit. z Monitor Momentary Purpose: Refer to Monitor. Operation: Hold down the programmed key continuously to enter this mode, and release the key to exit. Scan The Scan feature enables a two-way radio to continuously scan each channel for activity. Press the programmed Scan key to initiate scanning channels in the order as they appear in scan list. Status Indicator flashes green during the scan process, and solidly glows 17

when activity is detected and signaling condition is satisfied on a channel. Press the key again to exit scanning. When scanning is active, the radio will continuously scan for activity on scan list members. Once activity is detected on a channel, scanning will pause on the active channel for you to receive activity. The channels available for scanning are programmed by your dealer. No Priority Channel Providing that there is a scan list with 6 channels and all channels are non-prioritized, the normal scan operation would proceed in the following sequence, as shown in Figure 1. Figure 1 Normal Scan Sequence Priority Channel Scan If you prioritize Channel 2 as Priority 1, the scan operation would proceed in the following sequence, as shown in Figure 2. Figure 2 Priority Scan Sequence z Scan On/Off You can enter scan mode through any of the following two methods: (1) Key Operation Press the programmed Scan key to enter scan mode, provided that there’re no less than 2 members in the scan list. Press the Scan key again or power off to exit. 18

(2) Auto If Auto Scan is enabled for a channel, the radio will automatically enter scan mode when it is switched to this channel. When it is switched to other channels or powers off, the radio will exit from scan mode. z Talk Back This option defines whether users can talk back on the channel where scanning pauses. When the option is checked, users can do so. If the scanning does not pause on any channel, users may talk back on the predefined channel. z Priority Channel Scan This function enables users to scan the most frequently used channel so that messages will not be missed. The priority channel is programmed by the dealer via programming software. Contact your dealer for details. Note: Even though the radio remains on a non-priority channel, activities on the priority channel are still under monitoring. The radio will switch to the priority channel once any activity is detected. z Available Keys in Scan Mode PTT key, Volume Adjust keys [+] / [-], and 4 programmable keys of Squelch Off, Squelch Off Momentary, Monitor and Monitor Momentary. Busy Channel Lockout (BCL) This function can help avoid interference between radios operating on the same channel. When the channel is already in use, the radio will sound a continuous warning tone and return to Receive mode upon PTT press. To cancel the tone, release the PTT key. Low Battery Alert When battery power runs low, Status Indicator will flash red and a low-pitched tone will sound every ten seconds to remind users to replace the battery. VOX (Voice-Operated Transmit) With the dedicated VOX earpiece, you can enjoy hands-free communication. After this 19

function is enabled, the radio will automatically begin transmitting when you speak, and terminate transmitting when you stop talking, with no need of PTT press. Operation Steps: 1. Push the PTT/VOX switch on the earpiece to VOX. 2. Plug the earpiece into the accessory jack of the radio. 3. Press the programmed VOX key to activate the VOX feature. 4. When no signal is received, speak through the microphone of the earpiece and your voice will be transmitted. Operation Instructions: 1.
