  • Will my phone's warranty be void if I use an accessory manufactured by another company?
    If the accessory causes a problem with the phone, then the warranty is void. Many second party accessory suppliers and manufacturers reduce the cost of the accessories by eliminating safety circuitry, reducing strength, increasing tolerances and trying to use off-the-shelf components. Some accessory suppliers offer to pay for the cost of repair if their accessories cause the problem with the phone. Mitsubishi has tried to reduce the cost of accessories the last several years to discourage the use of second party accessories. Mitsubishi Wireless Communications Inc. (MWCI) does not endorse any second party accessories.

  • Are second source (non-Mitsubishi) battery packs as good as Mitsubishi's?
    Some are and some aren't. The heart of a battery pack is the cells inside. In order to save money, the cell manufacturer supplies these cells without labeling them. The consumer can't really see who the cell manufacturer is or the rating on the cells. Most second source cell manufacturers will meet the cell's specifications, but the following should be considered:

    A. How long is shelf life? If you can fully charge a battery pack, leave it set without using it for 72 hours (at normal room temperature), then use it and still get the same talk times/standby times, chances are it has good shelf life.

    B. Durability is how many times the battery can be charged and discharged. Each charge/discharge cycle will deteriorate the capacity somewhat. There's not a real good test you can do to determine this. This is where the reputation of the manufacturer plays an important part.

    C. Capacity is the amount of charge a battery pack can hold.

  • Where can I recycle my old battery?
    Mitsubishi Wireless Communications Inc., supports recycling of nickel-cadmium (NiCd) batteries through the National Rechargeable Battery Management Program. Call 1-800-8-BATTERY or visit WWW.RBRC.COM for the drop-off location nearest you.

  • The words "Enter Unblock Key" appear in the display of my phone. What does this mean?
    The Unblock Key is a security benefit for the end user. It prevents anyone from attempting to "guess" your passwords. Once a password has been entered incorrectly more than 3 times the phone becomes blocked. You must contact your Service provider (the company you pay your monthly air-time bill to). ONLY your Service Provider can supply you with the Unblock Key.
