2.Use the number keys to enter the channel number where you want to store the frequency, then press PGM again. Or, repeatedly press PGM until the desired channel number appears.

3.Use the number keys and DLY/to enter the fre- quency (including the decimal point) you want to store into that channel.

4.Press E to store the frequency.

Notes:

If you entered an invalid frequency in Step 3, Error appears, the channel number flashes, and the scanner beeps three times after you press E. Simply repeat Steps 3 and 4.

Your scanner automatically rounds the entered frequency down to the nearest valid frequency. For example, if you enter a frequency of 151.4730, your scanner accepts it as 151.4700.

If you entered a frequency that is already stored in another channel, dUPL (duplicate) and the lowest-numbered channel containing the dupli- cate frequency flash for about 3 seconds. To store the frequency anyway, press E again.

5.Repeat Steps 2–4 to store more frequencies into channels.
