Faults can be due to user error, inserting the batteries the wrong way round or not following the instructions. Damage to the remote control case (e.g. battery compartment catch) can occur at any time.
Electronic faults can develop on the PCB in the remote control (or IR receiver in the TV). This can be caused by poor connections, component failures and battery leakage / corrosion. The print on the keypads may also get worn.
The specification below provides the recommended improvements needed to improve product durability. They are ranked from bronze to gold based on the effectiveness of the change in improving durability, with bronze being the minimum and gold being the maximum.
Surface mounted components; soldered connections; durable materials
PCBs to comply with inspection standards and test requirements
* 10 randomly selected units to remain 100% functional after a series of 10 drop tests to EN 60068-2-31.
** A random sample of 1% of each batch of remote controls to be inspected to ensure 100% good quality moulding and 100% functionality with TV for: on-off, programme selection; volume control
Check the build quality of the remote control case and the clarity and durability of print on the buttons and case.
Ask for clear evidence of meeting the requirements listed, e.g.:
Improved reliability of components can reduce early returns and improve brand reputation which, in turn, can lower business costs and increase long-term sales.
To calculate overall cost savings for your business, use the WRAP cost/benefit analysis tool (currently in draft form and available on request).
Increase strength and rigidity for remote control casing
Small changes to mouldings and material specification should only add a few pence, assuming tooling change is minimal.
Remote drop testing
Drop testing of a small number of remote handset designs will add minimal cost.
Surface mount technology
The use of surface mounted components could add a significant cost depending on the volumes made and production techniques available in the factory of choice.
Remote control and PCB inspection on the production line
Inspection and functionality testing will add a small labour cost which should just be pence per unit.
