User Manual_D4






1.1 Important: Warranty terms specified by NiteCoreSA might differ from warranty terms specified by NiteCore International, as per user manual or other website. In such a case, NiteCoreSA warranty terms will apply as follow.     
1.2 Chargers and batteries carry a 1 year replacement warranty. Surge and lightning damage is excluded and not covered.
1.3 All flashlights (excluding low cost lights) carry (2) year replacement warranty (if purchased in 2015 or later, else only 18 months) with the possibility for a free factory repair from year 3-5 (this is a long process which sometimes takes up to a few months and we ask for your patience in this regard, as we carry all the international transportation costs.)
BUT flashlights under the value of R900 carry a 12 month replacement warranty (Such as the MT21A or MT2A) BUT flashlights under the value of R400 carry a 6 month replacement warranty (Such as the TUBE). No flashlights with non li-ion battery damage will be covered by the warranty.
1.4 NiteCoreSA do not carry warranty on items not supplied by us or one of our dealers. We are not a repair/warranty service agent for NiteCore, we are a reseller if you buy from us your warranty is with us if not – we are not responsible for your warranty and we will not offer any repair services at a charge either.

2.1 Should you find an error with your NiteCore product, please contact us first to allow us the opportunity to do debugging with you. If we cannot assist you telephonically or via email then you will have to send the unit to us for inspection. Please notify us of the tracking number, so we are aware and on the lookout for your parcel.
Before contacting us, please check the following.
A: Your battery is in fact fully charged and not inserted the wrong way around, in the flashlight or in the charger. Flat batteries may take up to 10 hours to charge, so please be patient.
B: All the components of the torch are tightly fastened to allow contact, specifically refer to the tail cap of most torches and battery compartment of the TMxx series.
C: The MHxx and P25 etc… needs the switch ON when charging, otherwise these units will NOT CHARGE.
D: Also check that your belt clip is not inserted at the wrong position, causing the tail cap not to close properly.
2.2 Within the repair period of a product, once it has been determined that a fault may exist, the client is responsible to deliver the faulty unit to us at the clients cost. (Also see point 2.1) The most cost effective methods are:
OR Postnet to Postnet +-R99,
OR Aramex at supported PickNPays, to our door R99
OR any other courier of your choice.
Please be sure though to shop around and get a quote beforehand as courier charges may vary significantly!
Once received, we will investigate the item and replace if necessary.
2.3 For units that carry a 2 year replacement warranty, the option does exist from year 3-5 to have the unit repaired at the NiteCore factory in Asia. In such a case, the client will be liable for the costs to deliver the unit to us, and for costs to have the unit returned from us. We will sent and collect the unit overseas for repair at our cost. Please be warned that this may be a very slow process and may take in excess of 3 months.
3.1 High Intensity flashlights will produce heat, some units will reduce brightness after a couple of minutes or at a certain temperature to reduce heat built-up. TURBO mode on most models is not sustainable for continuous use and is intended for sporadic use. Heat built-up is normal and unavoidable and will not constitute a warranty claim.
3.2 Returned items have to have a perceivable error in order to qualify as a valid warranty claim. In other words, when we test the item, we have to be able to detect a problem or malfunction. Items functioning normal or with undetectable errors will not be replaced.
3.3 Physical damage due to being dropped or being man handled and bent will not be covered by warranty. This will be a matter of interpretation by NiteCore. The 1.5m drop proof spec indicated on some products refers to the flashlight electronics being able to handle bumps and occasional drops etc.  It can be readily expected and anticipated that if your light is dropped, especially onto a hard surface or especially the higher weight lights like the tiny monster, the metal components might scratch or bend or the glass might crack.
This damage is NOT covered under warranty, and in some cases where the metal is bend, a repair will not be possible without replacing the entire parts of the torch and that will incur costs by the client.
If the LED or electronics seazes to work AND there is no prominent housing damage on the light, it WILL however be handled under warranty regardless of whether it was dropped or not.
3.4 It is strongly recommended to NOT submerge your flashlight. The IPX waterproofing is merely an indication that the flashlight is capable of handling day to day tasks such as walking in the rain, the warranty  excludes purposefully submerging the unit and it can be expected that at some point a leak will occur when  submerged.
3.5 Flashlights with battery leakage damage is not covered by any warranty.
