TK Accessories
TK accessories complement and extend the functionality of existing telecommunications hardware and provide investment protection through spare part availability. Adapters (TAE-to-RJ11, RJ11-to-RJ45, ISDN S0 adapters) allow existing phones to be used with different socket types – important when switching to all-IP or connecting imported devices. Replacement batteries for DECT cordless phones (NiMH, 600–1000 mAh, connector-specific) are cost-efficient alternatives to new device purchases, available manufacturer-specific (Gigaset, Panasonic, Siemens) or universal. Wall mounts and cable clips organise cabling and facilitate mounting of sockets, phones and patch panels on partition walls and cable ducts. Anti-tap adapters and DECT encryption solutions complement the security accessories range. |

Frequently Asked Questions
▶ Which replacement battery fits my DECT phone? DECT batteries are generally manufacturer-specific. Gigaset uses NiMH batteries with a proprietary connector (V30145-K1310-X383 or similar), Panasonic uses AAA NiMH or proprietary batteries depending on the series. Check the model designation of your handset and the battery type number on the original battery. Compatible alternatives can be found by searching for your device model. |
▶ What is a TAE-to-RJ11 adapter and when do I need it? A TAE-to-RJ11 adapter connects a German TAE socket (F-coded for telephone) with the RJ11 plug (6P4C) of an imported or older device (e.g. American phone, fax). It is needed when the terminal device has an RJ11 plug but the socket is TAE format. Adapters are also available for the reverse (RJ45 socket, TAE device). |
▶ How often should DECT batteries be replaced? NiMH batteries in DECT phones typically have a lifespan of 300–500 charge cycles or 2–4 years with daily use. Signs of an ageing battery: significantly shorter talk time (<50% of new condition), poor charging performance at room temperature, device becomes hot at low battery. Tip: never fully deplete DECT batteries and use deep discharge protection if available. |
