Battery Information
Initial Use
New batteries are shipped not fully charged from the factory. Charge a new
battery for 5 hours before initial use. The maximum battery capacity and
performance is achieved after three full charge/discharge cycles. If you notice
the battery power runs low, please recharge the battery.
Applicable Battery Packs
Toreducetheriskofinjury,pleaseonlyusethebatteryandchargerspecied
by HYT. Other batteries may burst, causing bodily injury and property damage.

Battery Information
Caution:
1. Toavoidriskofpersonalinjury,donotdisposeofbatteriesinare!
2. Dispose of batteries according to local regulations (e.g. recycling). Do not
dispose as household waste.
3. Never attempt to disassemble the battery.
Battery Tips
1. When charging your battery, keep it at a temperature among 5℃- 40℃.
Temperature out of the limit may cause battery leakage or damage.
2. When charging a battery attached to a radio, turn the radio off to ensure a
full charge.
3. Do not cut off the power supply or remove the battery when charging a
battery.
4. Never charge a battery that is wet. Please dry it with soft cloth prior to
charge.
5. The battery will eventually wear out. When the operating time (talk-time
and standby time) is noticeably shorter than normal performance, it is time
to buy a new battery.
6. In case the radio shuts off automatically at low battery power, recharge the
battery promptly, or the battery could suffer damage.
7. Remove the battery before you store the radio for a long time, or the
battery could suffer damage.
To Prolong Battery Life
1. Battery performance will be greatly decreased at a temperature below
0℃. A spare battery is necessary in cold weather. The cold battery unable
to work in this situation may work under room temperature, so keep it for
later use.
2. The dust on the battery contact may cause battery breakdown. Please use
a clean dry cloth to wipe it before attaching the battery to the radio.
Battery Storage
1. Fully charge a battery before you store it for a long time, to avoid battery
damage due to over-discharge.
2. Recharge a battery after several months’ storage (Li-Ion & Li-polymer

7
Battery Information
batteries: 6 months), to avoid battery capacity reduction due to over-
discharge.
3. Store your battery in a cool, dry place under room temperature, to reduce
self-discharge.

Basic Operations
Turning the Radio On/Off
Long press the Power Switch until an alert tone is heard to turn the radio on.
To turn the radio off, do the same as you turn it on.
Adjusting the Volume
You may adjust the volume level through Volume Adjust Keys [+]/[-]. Press
the [+] key to increase the volume, or press the [-] key to decrease the volume.
Selecting a Channel
Turn the Channel Selector knob to select a channel. Make sure the desired
channel number points at the Channel Indicator.

To transmit, press and hold down the PTT key, and then speak into the
microphone at normal voice level. Hold the radio about 2.5 to 5 centimeters
away from your mouth.

the following auxiliary functions to a short or long programmable key-press.
 None
 Power Adjust
 Monitor
 Monitor Momentary
 Scan
 Scrambler

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 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

15

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:
The LED glows different colors to represent battery strength levels:
Monitor
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.
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.

isnotsatised,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.
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 ashes green during
the scan process, and solidly glows when activity is detected and signaling
conditionissatised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gure8.
Priority Channel Scan
If you prioritize Channel 2 as Priority 1, the scan operation would proceed in
thefollowingsequence,asshowningure9.

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 Scan key again or power off to
exit.
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.
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
predenedchannel.
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.
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.
