The LED indicator will glow red indicating the battery is charging. 5. The rapid charger will fully charge the 1300 mAH NiMH battery in approximately 1.5 hours. The rapid charger will change to a green LED and switch to a trickle charge rate when a full charge is detected. The standard rate charger will charge at a constant rate (requires about 12 hours to fully charge a dead battery) and batteries should not be left in the charger longer than 15 hours. The LED of the standard rate charger does not signal a fully charged battery state. ! Do not leave the battery in the charger longer than 15 hours. .. When possible, charge the battery when it is fully discharged or, you have used it for the major part of its capacity. Otherwise the battery’s capacity could be temporarily reduced. Please see the paragraph “Memory effect”. .. Removing the battery before it is fully charged will temporarily reduce the duty cycle. Memory effect The NiMH (Nickel Metal Hydride) battery pack is made with a more advanced technology than a NiCd (Nickel Cadmium) battery. For this reason it is virtually free of what is called “memory effect”, which affects NiCd batteries. Memory effect causes a reduction in the battery’s capacity. However memory effect may occur if you regularly charge the battery when you haven’t discharged it at least at 50-70%. Memory effect can be easily avoided by following these simple rules: .. When possible, charge battery packs only when they are completely discharged. .. Do not remove the battery from the charger before the necessary time to provide a full charge. .. Provide at least two deep charge/discharge cycles per month. .. The best way to avoid memory effect is to use two battery packs and alternate their use with the radio. This will allow you to keep your transceiver in operation by replacing the battery pack when it is fully discharged. Erasing memory effect To erase memory effects try applying 3-4 deep charge/discharge cycles as follows: 1. Attach the battery to the radio and leave the radio on until the battery runs down and the radio turns off. 2. Switch off the radio and wait at least one hour and then turn the radio back on. Note that some energy remains in the battery, if the radio turns on. 3. Leave the radio on until the battery runs down again. 4. Repeat steps 2 and 3 up to three times or until the battery is well drained. 5. Fully charge the battery and check the battery capacity. If you believe some memory effect still exists go back to step 1. .. If the battery capacity does not improve after performing steps 1-5 three times, your battery pack is faulty or has reached the end of it’s life. Cleaning your radio Wipe the radio with a clean cloth to remove dust. If it is very dirty, you can use a damp cloth. Clean the battery contacts with a clean, lint-free cloth to remove dirt, grease or any other material, which may prevent a good electrical contact. If contacts are very dirty you can also wipe them using a soft pencil rubber (not hard erasers for ink). If you feel that battery contacts still aren’t making good electrical contact, please contact your dealer or communications coordinator. ! Do not use liquid, alcohol or aerosol cleaners. Optional Accessories ! When the accessory connector is not being used, the radio should be fitted with the supplied dust cover. The accessory connector uses a 3.5mm speaker jack and 2.5mm microphone jack. It is designed for the connection of two pin accessories. Any accessories to be connected to the accessory connector should meet the following requirements: 1. The speaker input impedance should be at least 8 ohms. 2. The microphone should be a low-impedance condenser type. 3. Any accessory should be of high quality suitable for professional use. ! Please do not connect any accessory if you are unsure it meets the requirements listed. You could damage your radio. .. Please consult your dealer or communications supplier for compatible accessories for your SP-400 series radio.
