User manual HUMMINBIRD DC5

[. . . ] Within the marine band, 10 channels are designated for continuous weather broadcasts. These channels are grouped into a "Weather Band" and designated "receive only" channels. The remaining frequencies are assigned for various purposes and given a channel number. There are basically two different channel numbering and frequency assignment schedules currently in use, which creates two different bands of frequencies: the USA band and the International band. [. . . ] Note: The nickel-cadmium (NiCd) battery contained in the DC5s battery pack must be recycled or disposed of in an environmentally sound manner. The incineration, land filling or mixing of nickel-cadmium batteries with the municipal solid waste stream is prohibited by law in some areas. Return the battery to a federal or state approved nickel ­cadmium battery recycler, Contact your local waste management officials for additional information regarding the environmentally sound collection, recycling and disposal of this battery or call Humminbird at the Customer Support number listed inside the rear cover of this manual. SECTION FOUR CONTROL FUNCTIONS Control of the DC5s are divided into three functional areas: The Power/Volume and Squelch controls are located on the top of the radio. The function control keys are located on the front of the radio. - Most control inputs result in audible, tactile, and visual feedback for positive actuation in loud environments. POWER AND VOLUME CONTROLS To power the DC5s for operation, turn the Power/Volume knob clockwise past the detent. The display will illuminate indicating that power is supplied to the DC5s unit. Continue turning the Volume knob until the desired audio volume is achieved. It may be necessary to adjust the squelch first, then adjust the volume once a transmission is received. To turn the DC5s off, turn the Power/Volume knob counter- clockwise until the detent is felt and the display is blank. ADJUSTING THE SQUELCH The squelch is commonly used to eliminate static and background noise from being heard. To adjust the squelch, ensure that the unit is powered and sufficient volume is available to hear the speaker. Wait for a period when no transmission is being received, and turn the Squelch slowly clockwise until the background static is eliminated. The squelch allows silent operation of the DC5s until a transmission is received. If the Squelch is adjusted too high, only the strongest transmissions will be heard. If the Squelch is adjusted too low, intermittent static and noise will be heard. USING THE PTT The Push To-Talk switch is located on the side of the DC5s and is easily accessible to both left and right hand users. A tactile click will be felt, and the display will show the TX (transmit) symbol indicating that the unit is transmitting. Care should be used to prevent the inadvertent actuation of the PTT switch. When storing the radio while powered, ensure that nothing comes into contact with the PTT. Inadvertent actuation will transmit a signal causing interference with other users, possibly interfering with an emergency broadcast, and will quickly drain the battery as well. SELECTING THE BAND Upon power-up, the last selected band will be in operation. The band, USA, INT (International), or WX (weather) is indicated on the display. Pressing the BAND button will toggle between these three bands. As with all controls, an audible chirp will be heard when the button is pressed. SELECTING THE CHANNEL Within each of these three bands there are a number of discrete channels. Pressing either key once will select the next higher or lower channel. Pressing and holding either arrow key will scroll through all available channels. USING DUAL WATCH Channel 16 is the normal monitoring channel for all maritime applications. In some instances, the government mandates continuous monitoring of channel 16. [. . . ] Note: Do not dispose of any battery in a fire because it may explode! SAFETY AND MAINTENANCE Never leave this or any electronic device in a closed car or trunk ­ the extremely high temperatures generated in hot weather can damage temperature sensitive components. TROUBLESHOOTING 1. Restore the full charge capability of the battery by exercising the battery from fully charged to fully depleted. This exercising prevents the memory effect and ensures maximum charge of the battery.
