Charging Operation

The battery is not charged at the factory, please charge it before use. Charge

the battery for the ﬁrst time after purchase or extended storage (more than

2 months) may not bring the battery to its normal operating capacity. After

repeating fully charge/discharge cycle for two or three times, the operating

capacity will reach the best performance. The battery life is over when its

operating time decreases even though it is fully and correctly charged. Replace

the battery.

Battery Charger Type

Please use the original charger by Midland; other models may cause explosion

and injure people. After installing the battery, if the radio red light twinkles, it

means that the battery is discharged; please charge it. .

Charging notes

• After the battery is charged to its highest capacity, don’t charge anymore.

• Do not short-circuit the battery terminals or throw the battery into ﬁre.

• Never attempt to remove the casing from the battery pack.

• Please turn the power o before charging. It will aect the battery life when

charging the power-on radio.

• If the radio still shows low power after the normal charge, please change

the battery.

• The average usage time of battery pack is 11 hours. Average usage time is

5% for transmitting, 5% for receiving and 90% for standby.

How to Charge

1. Plug the AC adaptor into the AC outlet, then plug the cable of AC adaptor

into the DC jack, the indicator lights orange for 1s and turns into GREEN-

--waits to charge.

2. Slide the battery or transceiver with battery into the charger; make sure the

battery terminals are in contact with the charging terminals well. LED turns

into twinkling RED---pre-charging begins.

3. Pre-charging for about 5 minutes, LED twinkles stop then charging begins.

4. It takes about 4 hours to fully charge the battery, when LED turns into

GREEN — fully charged.

CT310 Instruction Manual | 5

NOTE: When charging a power-on transceiver equipped with battery, the LED

will not turn into green to show the full charge status; it will be indicated only

when you turn o the transceiver: because when the transceiver is turned on, it

would consumes energy and the charger cannot detect when the battery has been

fully charged.

Charging Process:

Standby (self-examine orange lights

1 second when power on)

Green light

Pre-charging (pre-charging stage) Red light twinkles for about 5

minutes

Charging RED light lightens for about 4 hours

NOTE: Trouble means battery heating, battery short-circuit or charger short-

circuit.

6 | CT310 Instruction Manual

Charging Prompt

1. Self-examination: When charging, ORANGE light twinkles for 1 second

and goes out. That means the charger has passed its self-examination and

it can charge the battery normally. If the light remains orange or the red

light twinkles, which means the charger can not pass its self-examination

or charge the battery.

2. Trickle pre-charging: When the battery has been inserted into the charger

and red light twinkles (it means the remnant voltage is low), the charger

trickle charges the battery (pre-charging status), until the battery reaches

a certain electric quantity, the charger automatically turns into normal

charging. And if the red light stops twinkling, (it means the remnant voltage

meets a certain electric quantity), the charger will charge the battery

normally.

NOTE:The time for Trickle pre-charging does not exceed 30m. After 30m, if

the red indicator is still twinkling, it means it is unable to charge battery. Please

kindly check battery and charger.

removed from the radio. Its state of charge should be 50-100% charged.
