Frequently asked questions
Do both sides show exactly the same time?
Yes, a single internal NTP circuit drives both sides simultaneously. There is no perceptible offset between the front and the back.
How is the DF variant mounted?
Typically with a perpendicular bracket that places the display at right angles to the wall (flag mount) or hung from a ceiling chain. Both options are available at order time.
Why does the DF version have 4 digits where the regular NTDS24 has 6?
The double-faced design uses a more compact digit configuration for a balanced case. For 6-digit visibility on both sides, look at the NTDS26-DF or larger models such as the NTDS46-DF.
