Applies to: Identify PULSe 4K MINI exactly, not PULSe 4K or MINI SE. The documented MINI has one DVB-S2X tuner and an external IR-sensor connection. The manual’s illustrated menus use an older software version, so current menu names may differ. Product sales ended according to AB-COM; no end date is stated.
Match your symptom
| What you see | What to do next |
|---|---|
| Works with the door open | Check the IR path and external sensor. This repeatable difference is a better starting point than assuming the remote needs pairing or the dish needs alignment. |
| Front button and remote both fail | This is not enough to diagnose a bad remote. Check normal power/standby state and seek the exact receiver’s power support if it never responds. |
Work through these checks
Replace the battery pair correctly
For the supplied remote, fit two fresh AA batteries following the marked polarity. Do not mix old/new batteries or different types. If the compartment shows leakage or corrosion, stop using that remote and ask about safe replacement rather than scraping damaged contacts. Test a normal menu or channel key after replacement.
What the result means: Still no response: compare front control with direct IR control.
Try an unobstructed view
From close range, aim directly at the receiver’s front, not the television. Open the cabinet door only if safe and keep the receiver in a ventilated position. Compare the same key with the door open and closed. Do not move the box by pulling connected cables, and do not assume every smoked-glass or wooden door passes infrared.
What the result means: Direct control works: check sensor placement for the concealed setup.
Use the matching external IR sensor
Stop recordings and disconnect power before checking the sensor’s rear connection. Use the supplied or confirmed-compatible sensor in EXT.IR, leaving the sensor head where the remote can see it. Do not substitute an audio plug simply because it fits. Restore power, aim at the sensor and repeat the same key test with the receiver concealed.
What the result means: Sensor works: preserve that position and ventilation. Direct works but sensor fails: ask about the sensor/cable.
Confirm compatibility before replacing parts
If the front button works but fresh batteries and a direct IR test still fail, contact AB-COM with the exact remote and receiver identity. Ask whether a replacement remote and sensor support this original MINI. A MINI SE name, matching case or generic programmable-remote listing does not prove the same commands. Avoid resetting a working channel list while investigating control.
What the result means: Send the comparison results rather than a guessed diagnosis.
When to stop and get help
Stop for leaking batteries, damaged wiring, liquid, burning smell or unsafe access. Do not open the receiver or improvise an IR-sensor adapter. Do not factory-reset channels, alter LNB settings or flash firmware to test whether an obstruction blocks infrared light.
What to tell support
Report the exact remote, new-battery result, front-button response, direct line-of-sight result and whether the original EXT.IR sensor works. A remote problem and a channel-reception problem can exist separately.
Common questions
Which way should I point the remote?
At the receiver or its external IR-sensor head. The TV is not the receiver’s infrared target, and a concealed sensor cannot receive commands through every obstruction.
