Operation

Selecting a frequency

VFO Operation

Selecting an operating frequency using the HR2510's built-in VFO is easy. Make

sure that the F. Lock key isNOT depressed, and then simply rotate the dial to the

desired operating frequency. TheVFO will step in either 10KHz, 1KHz,or 100 Hz

increments. The step increment is indicated by a line under one of the 3 rightmost

digits of the frequency display. To change the VFO step, press the Span button

until the desired step isindicated by the black line. When using the VFO, you do

not need to manually select the band segment, as this is done automatically, so

that the tuning range is continous throughout the entire operating frequency

range.

Channel Select Operation

Youmay also select the operating frequency using the Channel 1\ and V but-

tons on the front panel or the microphone. The channel select buttons will select

any 10KHz channel in a band segment (50 channels in a; 28.0000 to

28.4900,b;28.5000 to 28.9900, c;29.0000 to 29.4900, and 20 channels in

d;29.5000 to 29.6900 MHz). The 10KHz channel frequencies are pre-pro-

grammed and cannot be changed. When stepping up or down, the unit will tune

to the nearest 10KHz channel. NOT to the dial frequency + or - 10KHz. When

you reach channel 50 (channel 20 in segment d), pressing the Channel 1\ but-

ton again will step to channel 1,conversely, when you are on channel 1,pressing

the Channel V button will step to channel 50 (channel 20 in segment d).

Toselect a band segment, press the Band button until the desired band segment

letter is displayed. It is displayed on the display above the channel number.

Ifyou press and hold down the Channel 1\ button, the HR2510 will continu-

ously step up through the pre-programmed channels. As it reaches channel 50,

(channel 20 in segment d), it will go to channel 1,stop momentarily, and beep to

let you know that you are at channel 1. In the same manner, pressing the Chan-

nel V key wil also do this, but itwill stop and beep at channel 50 (channel 20 in

segment d) to let you know.
