The problem affects Siemens M65- and C65-series phones. The handsets' software contains a glitch that causes its low-battery shutdown melody to sound at the highest available volume setting.
Siemens public affairs manager, Brad Voss, today said that if someone were holding the phone close to their ear at the time of the alert they "might get a bit of a fright". However, he later conceded that the recall was the prompted by concerns that the alert could cause hearing damage.
"In extreme circumstances -- depending on a person's hearing sensitivity -- we can't rule out that there might be a risk of that," said Voss.
Siemens today said it was yet to receive any legal claims against it for hearing damage in connection with the use of the phones.
Voss said the problem was found during testing at the company's German laboratory. However he was unable to explain why the company chose to undertake the testing.
The company was today still attempting to determine if the phones complied with Australia's sound emission safety standards.
The company currently estimates that 250 Australian consumers have purchased the phones, which have only been on sale locally for the last three weeks. All 4,000 of the phones to be recalled will require software upgrades.
Vodafone has chosen to call customers that purchased the handsets from its stores directly. Optus and Telstra customers will be contacted via SMS.
