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 aect 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.

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.

1 second when power on)

minutes

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.
