VHF55S INTRODUCTION

The Humminbird?? VHF55S represents state-of-the-art high tech VHF Handheld engineering, and is skillfully designed and constructed with the finest components. It is constructed to commercial- grade standards to give you clear, reliable communication.

The Humminbird?? VHF55S is available in three different versions:

???VHF55S.

???VHF55SC Camouflage.

???VHF55S Plus.

HOW VHF WORKS

The most popular method of communicating with other boats is via very high frequency (VHF) radio. In technical terms, this is similar to the way that commercial radio stations transmit. VHF equipment is relatively simple, and can therefore be compact and low cost.

To ensure that maritime users do not cause interference for other radio users, a part of the radio spectrum has been allocated specifically to this group of users. These reserved frequencies have been numbered; for example, Channel 16 (usually abbreviated Ch16) actually refers to a frequency of 156.800 mHz.

Because radio does not recognize geographic or political boundaries, and to make sure that boats traveling on international voyages can always communicate, the VHF marine band is the same worldwide. There are 55 international marine channels, a similar number of private channels (allocated on a local basis to commercial organizations) and some other unique national channels.

The United States and Canada employ a slightly different application of marine channels, using the same frequencies but allocating more simplex (one-way) rather than duplex (two-way) channels.

National channels include WX (weather) channels in the U.S., fishing channels in Norway and the marina channels M and M2 in the U.K. To make sure that your radio is fitted with the correct local channels, be sure to purchase type-approved equipment in the country of intended use.

BEFORE USING YOUR VHF55S

Before using your VHF55S radio, you should do two things:

1.Install the 6 alkaline batteries or charge and install the battery pack onto the radio.

2.Attach the antenna to the radio.

In addition, you may want to perform the additional optional step:

3.Attach the belt clip to the radio (optional).

1.Installing the Alkaline Batteries or Charging and Installing the Ni-MH Battery Pack

NOTE: If you are using alkaline batteries, you must make sure you have six fully-charged batteries.

NOTE: Rotate fastener as shown to remove battery pack from the radio. Lift the battery pack out and up from the bottom to remove it from the radio.

1a. If you are going to use alkaline batteries, remove the alkaline battery compartment cover and install 6 AA alkaline batteries. Re-install the cover to the battery compartment, then secure in place.

or...

1b. If you are going to use the Ni-MH re-chargeable battery pack, make sure that it is fully charged before trying to operate the radio. You can either charge the battery pack when it is attached to the radio or when it is not yet attached. To charge the Ni-MH battery pack, place it in the desktop charging cradle and plug either the AC or DC charger into the cradle, depending on the power source that you plan to use. You will know that the battery pack is seated correctly in the charger when the charging indicator LED lights up. You should charge the battery pack for 14-15 hours. Attach the battery pack to the radio when it is finished charging if you have not already done so.

CAUTION: The battery pack will continue to charge as long as it is in the charger and the charger is connected to a power source, so you must remember to take the radio/battery pack out of the charger when it has been fully charged. Overcharging batteries may result in damage to both the battery pack and radio.
