The Ericsson DT410 is ideal when you want to stay in touch in a non-office environment. It has a rugged IP54 plastic casing, making it tougher than the average cordless phone. It also means it is resistant to water spray, dust and soil. Designed for easy handling, the DT410 weighs just 195 grams including the battery. You can talk for 10 hours or be on standby for 100 hours without having to recharge the battery.
