ULTRALINK UL2000B 2. A blink code indicates the charge level of the battery: 1 = Battery is nearly empty . . . 5 = Battery is fully charged 3. Shortly after, a second blink code indicates the current channel setting for the transmitter: 1 = Channel 1 is selected . . . 8 = Channel 8 is selected When the blink codes have indicated the operating state, a constant glowing of the LED indicates the operational readiness. However, the battery is discharged and needs to be replaced when the LED continues to flash (see Chapter 1.1.4). 3.2.2 Channel setting Within a preset, you can easily select a channel by using the select switch relevant whether the transmitter is on or off. Changing the channel when the transmitter is already powered on During this procedure, the transmitter may not be set to mute! . In this case, it is not 1. Turn the selection switch to one of the positions 1 - 8, corresponding to the desired channel number. If a valid value is selected (i.e. neither 9 nor 0), the LED blinks quickly once as a confirmation. 2. Press the POWER button briefly. The LED flashes at a medium rate, corresponding to the channel number (for example, 5 times for channel 5) that has been set by using the select switch. If an invalid channel number is selected (0 or 9), the channel selected last remains selected. Changing the channel when the transmitter is powered off 1. Turn the selection switch to one of the values (1 - 8), corresponding to the desired channel number. 2. If you turn on the transmitter, the channel you selected is automatically loaded. If an invalid channel number was selected (0 or 9), the channel selected last remains selected. 3.2.3 Setting your own frequency A carrier frequency in the range between 798.1 and 805.9 MHz can be freely selected. This frequency is stored in a self-assignable user preset (Preset 1). The carrier frequency can only be set in 25-kHz steps. The frequency you select has to be a multiple of 25 kHz. If you select a frequency that is not a multiple of 25 kHz or does not lie in the frequency range between 798.1 and 805.9 MHz, the ULB2000 gives off an error message (the LED blinks quickly 5 times). 1. Engage MUTE. The transmitter can now be switched to the programming mode. 2. Turn the selection switch to 9 and confirm your selection by keeping the POWER button pressed for about 2 seconds. The LED indicates confirmation by blinking once with medium tempo and blinking once slowly. The transmitter is now in the programming mode and awaits the entry of a 6-digit frequency. 3. Enter all 6 digits one after another in the following fashion: Select the desired value on the selection switch, for example 4. If a valid value is selected, the LED blinks quickly once as a confirmation. This way, you can be sure that a correct value is entered (in regard to the frequency range and divisibility by 25 kHz) even before confirming your selection. Confirm your selection by briefly pressing the POWER button. If the end frequency value you entered is valid, the LED blinks quickly once more. If the frequency value is invalid, the LED blinks quickly 5 times, and the unit is no longer in the programming mode. In this case, start anew with step 2. After a brief interruption, a second blink code is given: the LED blinks corresponding to the value selected (in this case, 4 times) with medium tempo. 3. ULB2000 TRANSMITTER 13
