| **Alarm** | `_7 00 1_` | Shows alarm time (always in 24hr format) and on/off status on 5th tube (1=on, 0=off) and by display brightness (bright=on, dim=off). Use **Adjust** to switch on/off. Hold **Select** to set time (same way as **Time**). When alarm sounds, press **Select** to snooze, or hold for 1sec (followed by a short beep) to silence the alarm for the day. Options menu lets you restrict the alarm to your workweek or weekend only. In a power outage, the alarm will remain set, but it will not sound if power is disconnected at alarm time. |
| **Timer** | `__ __ _0` | A countdown timer, in hours, minutes, and seconds; or `0` when stopped. Can be set to the minute, up to 18 hours. Begins running as soon as you set it, and will continue to run in the background if you change to a different function. To cancel while running, hold **Select**. When timer runs out, press **Select** to silence. If power is lost, the timer will reset to `0`. Can be configured to work as an interval timer in the options menu (10), or as an appliance timer instead ([relay in switched mode](#hardware-configuration)). |

| **Day counter** | `_1 23 __` | Shows the number of days until/since a date you specify. Set the same way as **Date.** |
| **Temperature** | `__ 38 25` | Shows the temperature of the onboard DS3231 chip (e.g. 38.25°C – I think). May not be very useful as it tends to read higher than ambient temperature and its tolerance is low. Negative temperatures indicated with leading zeroes. |
| **Tube tester** | `88 88 88` | (Disabled by default.) Cycles through all the digits on all the tubes. |

### LEDs and Relay

Later UNDBs (v8 with mods, or v9+) are equipped with controllable LEDs, as well as a relay, which can be enabled in the [hardware configuration](#hardware-configuration) in **switch mode** (such as for a radio) or **pulse mode** (such as for a bell striker). If you have one of these UNDBs:

* The LED behavior is configurable in option 7, and can be set to switch on and off with the relay if enabled (great for a radio!)
* The alarm, timer, and strike signals can be configured to use either the beeper or the relay if enabled (options 11, 21, and 31 – strike can only use the relay in pulse mode).
* With the relay in switch mode:
* **Alt** will switch it on and off at any time (except in options menu). (Otherwise, **Alt** does nothing.)
* If the alarm is set to use the relay, it will switch on the relay at alarm time, and switch off two hours later. If **Alt** is used to switch it off, the alarm will be silenced for the day (skipping snooze).
* If the timer is set to use the relay, it will switch on while the timer is running, and switch off when it runs out, like a clock radio's sleep function. If **Alt** is used to switch it off, the timer will be cancelled. (The interval timer option cannot be used in this case.)

### Options Menu

* To access this, hold **Select** for 3 seconds until you see a single `1` on the hour tubes. This indicates option number 1.
