Frequently Asked Questions
What is the difference between an SBT clock and an SBTG clock?
The SBT digital clock operates in the 900MHz frequency range, while the SBTG operates in the 2.4GHz
frequency range. Clocks of different frequency ranges cannot be used together in the same system.
What happens to the digital clock if a power failure occurs?
If a power failure occurs, the display will shut off but the clock will continue to keep time with its internal
quartz oscillator. This oscillator will continue to run on a tiny battery backup for about ten years. In this
mode, it may drift from synchronized time by a few seconds for each year that the clock is without power.
Once power is restored to the clock, the display will turn on and display the time on the quartz oscillator. It
will correct this to accurate, synchronized time once a signal from a master clock is received.
What happens to the digital clock if contact with the time data source is lost?
The digital clock will rely on an internal quartz oscillator for keeping the time until time data is received.
While the clock is not receiving time data, its colons will blink.
How do I take advantage of the 3200/3300 chronograph functions?
The Chronograph functions can be engaged through Sapling's Elapsed Timer (part# SBD-ELT-001-0), or by
using a dry contact closure with the configurable user inputs (3300 only). Refer to the respective selections
of this manual for setup instructions.
How can I display "BELL" and "FirE" on the clock?
"FirE" and "BELL" are signals sent by the appropriate master clock. Refer to the master clock manual
for instructions.
For 24V clocks, what happens if voltage on the power line drops from 24VAC to lower voltage?
As long as voltage is above the minimum voltage needed for the clock, it will still function. If voltage is too
low, the clock display will dim, fluctuate, or not work at all. Please refer to the clock specifications, as each
clock, depending on its size, will have a different minimum required voltage input.
Will the wireless clock cause interference with other wireless devices?
No. SBT Series Wireless Clocks work on 900 MHz (2.4GHz for SBTG) frequency-hopping technology, which
allows the clock transmitters to avoid interfering with other devices operating on those frequencies.
Do I gain any advantages by having more than one transceiver on a locally-powered wireless
clock system?
Additional transceivers are only useful if you must mount a clock beyond the range of all other wireless
clocks. If all the clocks in the system are in range of each other, then there are no additional benefits from
having more than one primary transceiver.
