2.5.3 Setting the Radio Frequency
Spectracom offers both VHF and UHF versions of the TimeView wireless clocks. The
frequency ranges are:
VHF: 150 to 174 MHz
UHF Government: 406 to 420 MHz
UHF Commercial: 440 to 470 MHz
Mode steps 9 through 14 are used to select the frequency of operation. The step size
of the frequency selection is 2.5 KHz. Because there is no display digit for the tenths
Kilohertz place, the 1s KHz digit will advance to approximate the channel setting. This
approximation is for display indication only, however. Internally, the clock is set
precisely to the 2.5 KHz channel.
MODE 9
Pressing the Mode switch for the ninth time advances the setup process to
the frequency of operation parameter. Use the Set button to select the
desired 100s of MHz value.
MODE 10
Pressing the Mode switch for the tenth time advances the setup process to
the tens of MHz variable. Use the Set button to select the desired tens of
MHz value.
MODE 11
Pressing the Mode switch for the eleventh time advances the setup process
to the units of MHz variable. Use the Set button to select the desired units
of MHz value.
MODE 12
Pressing the Mode switch for the twelfth time advances the setup process to
the 100s of kHz variable. Use the Set button to select the desired 100s of
kHz value.
MODE 13
Pressing the Mode switch for the thirteenth time advances the setup
process to the tens of kHz variable. Use the Set button to select the desired
tens of kHz value.
MODE 14
Pressing the Mode switch for the fourteenth time advances the setup
process to the units of kHz variable. The minimum step size of the radio
frequency set up is 2.5 kHz, so the Set button will advance this digit as
follows:
0
=> 0.0
KHz.
2
=> 2.5
KHz.
5
=> 5.0
KHz.
7
=> 7.5
KHz.
