User manual COBRA MRHH400

[. . . ] Introduction Our Thanks To You And Customer Assistance Thank you for purchasing a CobraMarineTM VHF radio. Properly used, this Cobra® product will give you many years of reliable service. How Your CobraMarineTM VHF Radio Works This radio is a battery powered portable transceiver for use afloat. It gives you 2-way vessel-to-vessel and vessel-to-shore station communications, primarily for safety and secondarily for navigation and operational purposes. [. . . ] Allow the batteries to charge for 12 to 15 hours. WARNING Only the rechargeable NiMH batteries can be recharged. NOTE If the drop-in charger is to be used on a boat, Cobra® recommends you attach it to a shelf or bulkhead (using the screw holes provided) to prevent damage due to the boat rolling or pitching. Installation Batteries And Charger Maintaining The Battery Charge As you use your radio, the battery power icon will show the battery power remaining. When the icon begins to flash, it is time to recharge or change the batteries. You can monitor incoming calls while the radio is charging. However, you should remove it from the charger to transmit. Charging will be quicker if the radio is turned Off. CAUTION Use only the drop-in charger provided by Cobra®. Do not use the charger with alkaline batteries; only the NiMH batteries are rechargeable. Spent alkaline batteries must be discarded and replaced. It is a good idea to keep a set of fresh, high quality alkaline batteries with your radio. Should the rechargeable batteries become discharged and no electrical power source be available, you can insert the alkaline batteries and continue to use your radio until you can return to using the rechargeable ones.
