If your model number starts with AAH50R... the answer is yes. The CP200 could be programmed to match your RDU.

If your CP200 has a model number beginning with AAH50R it can be programmed to match the RDU2080d. If your CP200 model number begins with AAH50K, then the answer is no.

The letter R in the model number indicates it is UHF, and on the RDU2080d, the letter U in the model name indicates it is UHF. Both of these radios are programmable, and could be reprogrammed to match one another, if both UHF.

Best regards.

Short battery life can be due to several factors:

1) Short initial charge(s) when the battery was new.
2) Age of battery. Check your date code embossed on the lower portion of the battery below the label. On a three digit code the first number is the year, next two are the week of the year. If a four digit code the first two are the year. Example 142 is 2011 the 42nd week. OR 1142 if a 4-digit code. If you battery is more than 18-24 months old it likely needs replaced.
3) Short charging the battery by putting the radio on the charge too often, or with the radio turned on. Always turn the radio off when charging.
4) Poor connection with the charger. Clean your battery contacts on both the radio and the charger with a pencil eraser.
5) Excessive talking. Heavy talkers radios will run down quickly. It takes more energy to Transmit than to Receive. Using the 5/5/90 rule, your battery should go an 8 hr business day.

Note: There are 3 battery styles available for your radio. The one which comes with the radio is a 1100 mAH battery. There are also two others with higher capacities available.

Speaker is replaceable at a Motorola service center who does this model. (Current flat rate repair for the RDX series is $85.) The speaker is part of the front housing assembly, and would require the entire front to be replaced.

The RDU2080d is not waterproof, it is IP rated for water resistance. This being said, the general rule with any radio which has gotten wet is to get it dry quickly. Remove the battery pack, and do not attempt to use the radio until you feel you have gotten it dry. Some methods which have worked include using a blowdryer on the radio (not battery) or placing the 2 pieces in a bowl of uncooked rice to draw out the moisture. The absolutely best thing you could do is take or send it to a radio dealer who has the ability to open the radio and assess the damage and dry it out internally.

Once the radio is thoroughly dry, it may function properly, but you will always run the risk of corrosion growing on the component board and the need for service, or slow demise of the radio.
