I REFER to Mr Christopher Nyoe's letter, "iPhone users unaware of LCIs" (my paper, July 7).

We have contacted Mr Nyoe and explained to him Apple's warranty, with regard to liquid damage.

Each iPhone has a built-in Liquid Contact Indicator (LCI) that determines whether liquid has entered the device.

When the device has been exposed to enough liquid to cause damage, the LCI turns red.

We would like to explain Apple's warranty for iPhones.

As an official distributor of the iPhone, we comply with the warranty policies prescribed by Apple.

If an iPhone is damaged by liquid, the repair is not covered by both Apple's one-year limited warranty and extended warranty.

We took the initiative to provide feedback to Apple on LCI conditions in Singapore.

Hence, last May, Apple extended an Out-of-Warranty service option to our customers.

This service option covers LCI-related issues and we have since implemented this service.

An iPhone that has failed due to liquid damage is eligible for Out-of-Warranty service, and affected customers can purchase a refurbished iPhone for $350.

We inform our customers about this by giving them a copy of the advisory - which is available at http://support.apple. com/kb/HT3302 - when they purchase their iPhones from our stores.

We thank Mr Nyoe for his feedback.
