CARE GUIDE-APPLIANCES 06-DIGITAL LOCK
SOLITY MARVEL MV-3000BK
Tenant Usage + Upkeep Guide
1️⃣ Daily Usage – What Tenants MUST Follow
✔ 1. Always CLOSE the door gently
Do NOT slam or push hard.
Why:
This model’s latch mechanism is sensitive
Slam force will misalign latch + striker plate
Causes failed locking, error beeps, or door stuck
✔ 2. Use PIN code with FIRM, slow taps
Avoid:
Fast tapping
Fingernail taps
Smudging digits
This prevents sensor wear + reduces error entries.
✔ 3. ALWAYS check the lock engages properly before leaving
Standard check:
Pull the door gently
Ensure lock is engaged
Ensure handle resists movement
This prevents “door didn’t lock properly” incidents.
2️⃣ Weekly Care – Tenant Responsibilities
✔ 1. Wipe keypad and biometric sensor
Use:
Dry microfiber
NO water
NO chemicals
✔ 2. Check battery indicator
If the lock beeps or shows low battery icon → CHARGE THE LOCK IMMEDIATELY WITH ANY PORTABLE POWER BANK CHARGER
✔ 3. Ensure door alignment stays clean & obstruction-free
Check the area around:
Latch
Strike plate
Door frame
No objects or debris must be stuck inside.
3️⃣ What Tenants MUST NOT Do (Critical Rules)
❌ 1. Do NOT slam the door
Destroys latch alignment → lock will stop closing or jam.
❌ 2. Do NOT force the push-pull handle
If lock doesn’t open:
It’s a verification issue
NOT a mechanical issue
Forcing handle = expensive repair.
❌ 3. Do NOT attach hooks, bags, or weight to the handle
Common mistake → breaks internal mechanism.
❌ 4. Do NOT attempt to “reset” the lock or open battery cover unnecessarily
Unauthorized tampering = chargeable.
