To charge using the MGC400 Multi Unit Charger accessory:
The (optional) Multi-Unit Charger (MUC) allows the drop-in charging of 6 radios or 6 batteries from a single AC outlet.

1. Plug the barrel plug on the adaptor cord into the connector on the back of the charging base.
2. Plug the AC adaptor into a 120V AC wall outlet. Make sure the AC outlet has power.
3. The charger's LED's turns green when power is present.
4. Make sure the battery contacts and charge terminals are clean and in good condition.
5. Slide the radio with installed battery, or a spare battery without radio, into the charger being careful to align the slots on the battery with the tabs inside the charger opening.

PRIVACY CODES
CTCSS (Continuous Tone Coded Squelch) and DCS (Digitally Coded Squelch) allow several users to share the same channel frequency without disturbing each other. With CTCSS or DCS enabled, the channel is muted to all incoming signals unless they carry the same CTCSS or DCS tone. When a transmission with the same tone is received, the channel un-mutes and the voice audio can be heard. When the transmission ends the channel becomes muted again. Transmissions that do not have the same tone will not be heard.
Your MB400 radio has 142 Privacy Codes, which can be used on any channel. The selected Privacy Code may be different for each channel, but must be the same for a channel on all radios you wish to talk to. Programming a new Privacy Code overwrites any previous code programmed.
Privacy Codes can be set using the FREE programming software that can be the www.midlandusa.com website.

• You will not be able to hear or talk to other radios that do not match your frequency and Privacy Code by channel and frequency.
